[Emc-users] Need for speed
Hi I have recently built a 1500mm x 1500mm gantry style router. I am using EMC to run three FL86STH156-4208 11.96 Nm stepper motors, with 16mm x 4mm pitch trapezoidal screws. The gantry weighs some thing like 70kg. It works pretty well except the fastest movement I can achieve for x and y is around 15 mm per second before the steppers start complaining. I know the spigots on the end of the screws were not turned very concentrically, (I used a crappy lath)...could this be the reason for the lack of speed?

Re: [Emc-users] NAMES and Flash Drive devices
Copying to user-provided flash drives instead of handing out CDs is a great idea, especially because it makes the user participate actively rather than just grab reflexively. Although that's true, I think trying to do anything that smacks of system administration while on the show floor is doomed to humiliating failure. Most of the time, flash drives Just Work under Linux, but there are a wide variety of flash drives and some require specific care feeding. All of us have the personality flaw that requires us to solve problems and there's nothing more compelling than Showing Off Our Sysadmin Chops. The inevitable result is being elbow-deep in the guts of the OS, desperately trying to write the victim's USB drive, while causing untold collateral damage. Worst case: neither his USB drive nor your system are ever quite the same afterward -and- you blew half an hour getting there. Better to keep a stack of CDs under the table and hand one out to each interested prospect. While the CD might not be readable in his drive, you can fix that up after the fact. I would not, under any circumstances, use a Windows box for USB-drive duplication, as you'd almost certainly propagate the malware brought to you by an unsuspecting victim.

Re: [Emc-users] Need for speed
I have 200oz-in stepper running an ~35lb gantry using a 24V 12A PS. Each axis is receiving upto 3A using a hooby board. I am able to achieve cut speeds over 2 ips. I know I can get more if I tuned my gantry better, but heck - its only plywood. Doing some conversions, it sound like the steppers you have are ~1700 oz-in units. From my reading, the higher the torque the less top end speed unless you have timing belts to take advantage of the steppers. I also thought a machine requiring this size stepper was better served by servos? Some things to check: Gantry racking Pretensioning your lead screws Proper alignment of your leadscrews and bearing mounts Proper alignment of your motor / leadscrew Proper tightening of all axis rails This weekend after 10 minutes of messing with leadscrew bearing mounts and the lovejoy couplings, I went from a lousy 0.5 ips to over 2 ips. My steppers even sound happier now. Hope that helps some. -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.

Re: [Emc-users] No whine from the steppers
Gentlemen, although I understand much more now about EMC than in January, I still have problems with my stepper motors. They do pretty much what they ought to now ( I can scribe the AXIS logo with my PCB drill), but their sound still isn't what we all are used to from photo copiers and other stepping gear. My motor gives about a constant tone, which is not very distinct, however. The turning isn't easy going, I seem to feel a reluctance to follow each step impulse. I reduced the problem to the X-axis only to make it simpler to follow. At any rate, there is no singing or whining of the motor, I can't hear the familiar accelerating and decelerating sound, it makes no difference in sound when I change the stepping frequency. I can vary all the params in stepconf and test their axis within the program, it makes no difference. Understand me right, the motor sure varies speed and acceleration visibly, so the configuration shows effect all right, but it's not an audible change. And I don't think I can rely on the true count of steps, surely not when it comes to work under load. This phenomenon is what I called rattling in a former thread (end of Jan.). I tried, as I was adviced then, to eliminate doublestep, I changed polarity of puls an direction, varied pulse and pause times, chose extreme pulse and pause rates manually editing the hal and ini files, it all makes no change in this behaviour. The driver card can't be the reason because with my old DOS program things work still ok. What can be wrong with my setup?

Re: [Emc-users] Automating emc2
I suppose my initial idea of using emcrsh as part of a shell script that starts emc is coming out as the preferred solution for homing the machine automatically upon startup. This is not too difficult to do. I hear the suggestion that turning off the stepper power is a mistake due to positioning errors. Since my machine moves a ball bearing through sand, micro accuracy isn't that important (it doesn't mean the machine can't do it!) The table will sit for long periods of time doing nothing and then people will start interacting with it. I have to weigh constant current to the steppers vs. turning off the power and occasionally re-homing. The need for the request will be figured out over time. I can also use a script that occasionally polls emc using emcrsh to determine when a run has finished and then invoke some action.

[Emc-users] VB: BIG CNC machine for making small airplane?
Hello all! I am new to the list but have been checking out the project for quite a while. I am thinking about building a ultralight aircraft by 1) designing a 3D object 2) Making real by CNC in foam 3) building skin in epoxy/fiberglass. Much like a surfboard! Stringers and such would of course be needd. They could be pre-added to the core. The thing is, a BIG machine CNC would be needed. Does anyone have experience building such a big CNC machine? It would need to work object several meters large. Preferable up to 4-5 meters. I am thinking some serious welding is needed for a solid frame but how to make suitable sliding rails that are long? And are there tooth belts that long? Perhaps a cograil? How to maintain minimum play? I am sure all these problems are solved since i have seen big sailboats beeing protyped on TV, but how to make a DIY version? Ideas anyone?

Re: [Emc-users] Automating emc2
If your driver chip has an idle current circuit, you can let EMC manage power to the steppers. I currently use this function and this past weekend, the machine was up for 8 hours with no activity. Touched the steppers and they were stone cold. Hit the run button and they were humming along. -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.

I am sure all these problems are solved since i have seen big sailboats beeing protyped on TV, but how to make a DIY version? Ideas anyone? Peter Cutting foam makes things easier since the machine doesn't have to be extremely rigid. But it will still be a very expensive project. I suspect cost is somewhat proportional to the volume of the work envelope. So a machine that can work 5 meter parts isn't 5 times as expensive as one that works 1 meter parts, but somewhere between 25 and 125 times as expensive. There are all kinds of creative possibilities for reducing the size, but first you need to define your requirements in some more detail. How much accuracy are you looking for? Achieving 0.01mm over a 5m workspace would be extremely expensive. Even 0.1mm would be hard to do cheaply. If your tolerances are closer to 1mm, things get simpler. How many axes do you need? A three axis machine is usually simpler and less expensive than four or five axes, but smooth curvy airplane shapes might be hard to do with three axes. How big does the workspace really need to be? Does it need to be a 4 x 4 x 4 meter cube, or can you get away with one or two shorter dimensions? For example, wings are long, but only moderately wide and not very tall at all. Where will you be building this machine? A machine that can cut objects that are 4 meters tall might require an 8 meter ceiling - it won't fit in your garage. If you have a suitable space (such as a small hanger), an interesting possibility would be a cable hexapod. EMC2 is capable of running such a machine, although configuring and homing it is non-trivial. A cable hexapod can be very inexpensive per cubic meter of workspace compared to anything else. The tradeoff is limited accuracy and limited rigidity. Alex has made a (tabletop sized) version with three cables: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Alex_Joni's_Toy Alex's tripod uses three cables to define a point in space - for machining, you need to control both the location of the tool-tip (a point) and the orientation of the spindle. That requires six cables. But it can be done - the original NIST version of EMC did it in the late 90's. No matter what approach you use, such a machine is a non-trivial engineering exercise. It sounds like you aren't afraid of big projects (an airplane is a big project). Just make sure you know what you are getting into.

[Emc-users] Backlash and Lost Steps/Frozen Motor
Hello all, new to group. I am in the very final phases of completing my cnc setup. The last thing I did was set a backlash setting in my ini file. After doing this and running a test, I noticed that the x-axis motor started freezing up and loosing steps. Everything was working perfectly before I used a backlash number. I was wondering if anyone else has encountered this here. I am thinking that the backlash repositioning does not adhere to whatever acceleration values you have set on your system and therefore locks up. Is there a way to change the acceleration value of the backlash? Will lowering the acceleration of the system help this?

Is there a way to change the acceleration value of the backlash? Will lowering the acceleration of the system help this? Any input is appreciated! This is a known problem, one that unfortunately doesn't have a simple fix that we could apply to the code. The backlash compensation move is limited to 50% of the accel limit in the ini file. The compensation move is added to whatever movement is required to machine the part. If the part program is using 100% of the accel limit, then the sum of the two can total 150%. The only workaround is to reduce the ini file acceleration limit to 66% of what you have determined that your motors can handle. That way, you have a maximum of 66% main program accel + 33% backlash accel = 99% which your motors can handle.

Update from the photo front - Ok, I have now sorted out the multitude of issues which have plagued me from the start of this endeavor. I knew I had purchased a large mailbox amount on my hosting package - only problem was when I set it up _I_ didn't allot it a sufficient size, so instead of a 100MB mailbox I had a 10mb mailbox and 75MB unallocated. To top it all off I had set my client to leave copies on the server for 5 days so once it filled Saturday into Sunday, it was tits up. SO - If you have tried to contact me and gotten a bounce back message or no response whatsoever, and are still willing to provide images, go ahead and contact me again.

But the box was full from sometime late Sunday (east coast time). I apologize for the unprofessionalism this started off with. I made too many assumptions, thereby making an @$$ out of myself when all I wanted to do was help and use a talent and equipment at my disposal to promote EMC. This sort of error would have been catastrophic had it been a full fledged business (which one day I intend it to be). So my apologies to everyone, especially those who put up with trying to get files to me and being patient while I tried working out my bugs.

Some of the machines received so far are very inspiring for me in seeing the creativity not only in the work they are producing but in the machines themselves.

aaron moore wrote: Hi Jon Can you tell me what midband resonance is. Could it have anything to do with leadscrews that vibrate/ whip around a bit Stepper motors have poles, where the magnets and coils interact to form the full-step positions. With the magnets pulling on the toothed stator plates, there are those detents you can feel in the motor. (When the coils are energized, these detents get a LOT stronger.) So, the motor has fixed positions built into it by the magnetic circuits inside. These act like springs, when the rotor is deflected from the center of the detent it will return when you let up on the shaft. Now, the rotor also has mass, therefor angular momentum. Add momentum to a spring, and you have something that can bounce back and forth. When the step rate approaches this natural resonant frequency, you have a very unstable condition. If the motor is driven at that frequency for a while, without enough damping, the resonance builds until it is strong enough to jump over 4 full step positions. Then, the motor is capable of running backwards, stalling, or all sorts of erratic behavior. Gecko has a patented scheme to damp this resonance electronically, and all I can say is it really works! Due to that, I have a strong suspicion you are not using a Gecko drive, or any other with mid-band damping. Back in the old days, before microstepping, there were a variety of fluid dynamic dampers that were attached to stepper motor shafts to fight this. Many of them were basically a thick disc with an annular cavity with a big steel washer sealed inside, with a bunch of grease packing the cavity. Others had a steel washer attached to a thin disc with a rubber pad. All involved some kind of viscous damping scheme. If you are using a full- or even half-step drive, I think this definitely is your problem, and you may find it hard to fix with that type drive.
