[Emc-users] What ACCELERATION values can I expect from a Bridgeport Interact mill
I have been using the mill, today, for making a part where most of the time was spent engraving small text. Due to low setting of acceleration (which I picked out of abundance of caution), the mill could not reach the desired speed when engraving those letters. So, for a big Bridgeport Interact mill, what kind of acceleration for X and Y are possible? i -- Sell apps to millions through the Intel(R) Atom(Tm) Developer Program Be part of this innovative community and reach millions of netbook users worldwide.

Re: [Emc-users] What ACCELERATION values can I expect from a BridgeportInteract mill
I would recommend setting up Hal Scope to show the commanded position and the actual position (or perhaps following error or velocity error if there is a setting for that), then program some back and forth motion, increase acceleration until the following error grows at the point where direction is reversed. Then back off acceleration until the machine no longer has difficulty following the command. Simply put, accelerate as fast as the motor and drive are capable of, using Hal Scope to find that speed. If you do that and it seems excessive, you can always lower it.

[Emc-users] Monitor cable lengths
We plan on using 2 24 LCD monitors on our lathe. 1680x1050 is the resolution of some we have in house. I was wondering if anyone can share their experience with DVI-D/DVI-I cable lengths past the specification's 5m/16ft. I think I trust some comments on here than more anonymous comments elsewhere. We replaced a crt in one lathe with a lcd, it shows some strange sync issues the crt never had. And that's only lowres 15 vga. So it would be nice to know what to expect with a higher resolution signal. Also interesting how some sites also recommend vga over dvi-d/i for longer cable runs. My expectation was a digital signal can be run longer than an analog one.

[Emc-users] My waterjet machine, retrofitted to EMC (also - a sales ad)
Hello! Following other members on this list, I also would like to share information about my abrasive waterjet cutting machine that has been converted to EMC2. Originally it was produced in 2001 by PTV, working envelope is 3000 * 2000 mm. Here are first 3 pictures I have taken: http://www.cutting.lv/en/waterjet-pictures (if anyone is curious to look around my webpage, then LV version contains more pictures, showing different completed jobs, apologies for my laziness, but all my clients are from LV) What I have done: 1) first of all, a PCB was created that converts usual step/dir signal to a step/dir signal in a twisted pair (servo drives accept only 24 V step/dir signal or 5V step/dir signal in a twisted pair; 2) PCB with optoisolators was created to join existing limit and homing switches with EMC. All the existing hardware is working with 24V signal level, which is not directly compatible with LPT port; 3) relays for control of water jet and abrasive have been added. Water jet is a spindle for EMC and abrasive is coolant flood. 4) I installed EMC2 :); 5) I created new panel for control cabinet, where: 5.1) old 10 monitor is upgraded to 17, 5.2) I also have duplicated 2 buttons and 3 signal lights from the pump - it has made my life much easier, as I do not have to run to pump to switch it to high pressure and back to low pressure after cutting is finished (it is not recommended to stay in high pressure mode, when not cutting, as it puts a lot of stress to high pressure tubing - water pressure is ~ 4000 bar) 5.3) I have added 2 switches for manual control of waterjet and abrasive together and abrasive only. It allows me to turn off jet and abrasive manually, when running file as well as I can easily switch to water only cutting, because g-code always contains both commands - for water jet (M3 and M5 respectively) and for abrasive (M8 and M9 respectively). It can now be managed easily and effectively. 5.4) I cut, welded and painted the new sheet for a panel. It twisted during welding, so there are few dents from hammer as I tried to straighten it out :) Painting has not covered them completely. 5 axis cutting capability is still a work-in-progress due to different difficulties with stepper motors and my Gecko drives. I still owe a lot of thanks to Andy Pugh, who devoted a lot of time and effort to the kinematics module that handles all the compensating moves, as well as takes tilt angle from G-code (where it is included as a command for A axis), then calculates tangent of the nozzle's movement - C axis and then converts all that to actual commands for A and B axis. First tests indicate that the module is working, but more tweaking is necessary to make it more precise. One of the reasons I am sharing all this information is that I would like to sell this machine - my financial position is insufficient to cover my bank payments. If anyone is interested, please do not hesitate to contact me. If there are any other things that You would like to see - servo motors, pump or anything else, let me know and I will post the pictures in my homepage. Unfortunately max available size for pictures is 800 * 600 pixels.

[Emc-users] Emc2 Safe Zone ?
We are wondering if emc2 can have a Safe Zone. We would like to define where chuck and tail stock are and keep the machine from smacking into those. Like an extended soft limit. Possible difficulties I see in this is that often we get the turret within .050 of the tail stock quill. Which means this safe zone would require a rather fine grained resolution in Z, to avoid false alarms while still being able to stop the actual crash. Is there something emc2 already has that could be used for this?

I have no idea what values other people are using, but I'm sure you can go higher than 3.

Re: [Emc-users] What ACCELERATION values can I expect from a Bridgeport Interact mill

[Emc-users] Do I understand the EMC/HAL/UI architecture properly?
This is probably going to seem like a ridiculously obvious question, but before I start buying and cutting too much material I wanted to double-check my understanding of how the various parts of a complete system interact. The project I'm working on is to build a really comprehensive physical interface panel for my milling machine. Namely I want to have dedicated buttons for lots of functions, some with LEDs to indicate current status. For instance, I'd like a button that toggles flood coolant on and off, with an LED that shows whether it's on or off, (in case I don't happen to notice the lube spraying everywhere) I've gotten the basic HAL-Arduino example from the Axis unpy.net site to work, and I've used the Arduino for other things before, so I feel like I have at least one idea of where to start on the hardware side. Now, my question is what happens with the various GUIs like Axis if there is something like my keypanel in the system. Does Axis (or TkEMC, etc.) actively poll HAL every so often to see if the status of things (like flood coolant) have changed? Ideally, I'd like to see the following sequence of events occur: 1. Flood coolant is off. Both the control panel LED and the Axis UI show flood coolant off. 2. I load and start a G-code program which uses flood. The LED turns on as the flood G-code is executed. 3. I press the flood button on the keypanel which sends a signal to HAL to toggle the flood coolant off. 4. HAL shuts off the flood coolant. The keypanel LED goes out and the Axis UI shows flood coolant as off. Essentially, I think my question boils down to whether I understand HAL correctly as being the source of truth for both my physical keypanel as well as for the GUI, or whether the GUI thinks it's the only thing affecting machine state? -- Sell apps to millions through the Intel(R) Atom(Tm) Developer Program Be part of this innovative community and reach millions of netbook users worldwide.

Re: [Emc-users] Monitor cable lengths
When the analog signal degrades it still maintains a high level of information compared to a degrading digital signal. Compare that with a lithium Ion Battery driven tool and an older NiCad driven tool. The Nicad performance degrades slowly and in case of a drill you might manage to squeeze one or two of those last holes out of the tool. The digitally controlled Li battery will stop form one moment to the other. So, analog becomes gradually more 'fuzzy' and digital either works, or not in a rather catastrophic way. Having that said, the focus is clearly on signal quality. You can either switch to fiberglass transmission with encoders and decoders on either end, or better cables (makes a HUGE HUGE difference!), signal amplifiers, broad band cables with en and de coders. You can reach FAR but the distance comes with a price. 10-20 ft should be doable with cables made for the signals intended. And as expected... those will not come from China and cost money.

[Emc-users] Play/Pause and One Step buttons?
My mill has two buttons, one is a green one and another is red. The way I would like to use them is as Play and Pause. As follows: * If a program is not running, or is suspended, green button starts it. * If a program is running, green button has no effect. * If a program is running, red button suspends it. * If a program is not running, or is suspended, red button has no effect. In other words, I want to use them as Play and Pause buttons, like on a VCR. I also have another button that I want to use as do one G-code instruction button. When pressed, one G code instruction will be executed and then execution will stop. Am I on the right track with this logic and if so, what sorts of Axis elements should I use? I am finally able to work on them because I removed a shipload of unused wiring from the pendant arm and can deal with extra wiring without the horrid mess of 100+ other wires that were in the arm. This is because the old control was in the pendant, but the PC with EMC will be in the main cabinet. Also, for simplicity, for these extra signals, I wants to use a Cat6 cable, because of its compactness. There is no problems with those wires twisted together, right?

I would like to control speed override with a rugged encoder type rotary control. A thought that I have played with in my mind, and gone as far as to order a few parts, is to use a more or less std small stepper motor with 12 or 24 volt rated coils, as an encoder by feeding it to a pair of comparators which should give a quadrature A B output. I haven't worked out a 100% reliable method of protecting the comparator inputs from the over-voltage a fast spin of the knob on the motor shaft would feed them, nor have I worked out the most reliable hysteresis feedback to prevent low level vibrations and such from outputting spurious signals. But, based on the fact that the average $3 stepper motor is also a heck of a good generator, I see no reason why it couldn't be done. Suitable stepper motors can be had for small change. I have a box that I was going to use that would hold one encoder/motor for each of the 4 axis's I have, a bit big, but with one knob per axis I think it would be more usable than a game pad that I have hooked up now. A 5th motor could be installed for feed rate control, and a 6th for spindle speed is not a huge problem a long as I could get some help with the hal stuff. But my box would be pretty crowded by the time I shoehorned 6 of the motors I have right now into it. So its an idea I'm tossing out because I could do all 6 of those for less than a single pendant with one dial at the current prices. -- Cheers, Gene There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

I would like to control speed override with a rugged encoder type rotary control. A thought that I have played with in my mind, and gone as far as to order a few parts, is to use a more or less std small stepper motor with 12 or 24 volt rated coils, as an encoder by feeding it to a pair of comparators Gene, I have a feeling that what I need, can be bought for $20-50 at Digikey as a complete package. (hand controlled encoder) Am I mistaken? i which should give a quadrature A B output. I haven't worked out a 100% reliable method of protecting the comparator inputs from the over-voltage a fast spin of the knob on the motor shaft would feed them, nor have I worked out the most reliable hysteresis feedback to prevent low level vibrations and such from outputting spurious signals. But, based on the fact that the average $3 stepper motor is also a heck of a good generator, I see no reason why it couldn't be done. Suitable stepper motors can be had for small change.

Re: [Emc-users] What ACCELERATION values can I expect from a Bridgeport Interact mill
Jon, I do have those strong SEM servos. 30 amp peak, 145v. I take it as a hint that my machine is capable of more. I am afraid that I may have set DIP switches on some of my axis drives to limit current too much. I will revisit it. It did make engraving faster, perhaps 2x faster or so. i On Sun, Aug 29, 2010 at 11:53 PM, Jon Elson el...@pico-systems.com wrote: Igor Chudov wrote: Jon, I messed around a bit until I saw max following error at about 0.0012.
