Re: [Emc-users] stepConf configuration | EMC conversion
Hi Thanks to Ted and many others on the group I have had most of my questions answered. I finnaly got all my parts and am excited to be wiring my cnc today. I am converting an old (90's era) CNC router to emc. I purchased a break out board to wire to the existing ib106 drivers. This following photo shows the guts as they are now: http://www.forsalesticker.com/oldGuts.jpg So I am replacing that board in the middle with a breakout board and wiring to the drivers. Now I have a few noob type questions - 1 - What guage of wire should I use to go from the break out board to the drivers? I have some wire from a cat 5 cable but it seems very tiny - should I use something fatter? 2 - The power from my power supply (very top right in the photo) goes to some other board (what the heck is that thing anyway?) And then there is a plastic connector from the what the heck board to the getting replaced board that has a white and black wire. When the power is on I get 11.7 volts DC on those 2 wires. So my break out board is asking for ground and power (+9 to +24 V) Can I assume that black is power and white is ground? Or is white neutral and I need to get ground from something else? Is there a good method to test this using a simple multimeter? Thanks for the help.

This is because the very first power wires were insulated by strips of linnen soaked with guttappercha and natural rubber, filled with soot. Hence: black colour for the dangerous one. House wiring was done with free dangling wires on wall mounted porcelaine insulators just below the ceiling (I've seen houses like that). The neutral wires weren't insulated at all, later they got a grey coating (less soot in them), still later blue as artificial dyes came up. This coating made it possible to collect the two wires in one single cable. Insanity? Consequence!

Re: [Emc-users] stepConf configuration | EMC conversion
Ted - Thanks for your advice. This helps very much. I have a few more questions below. The very first thing you need to do to make informed decisions is to get as many datasheets as you can; Thanks for the sheet on the drivers. Do you have any advice on how to locate info on the stepper motors? I have googled for the steppers ( eastern air LA34BJK-P500 ) and havent found that model number anywhere. The closest thing I found was at http://www.ni.com/devzone/advisors/motion/eastern.htm but that site does not include the correct model. Don't stop there - if there are limit switches, get info on them. no limit switches. (bummer) Spindle drive/controller, same thing. My spindle is only a PorterCable router. There is only a on off switch that is wired to the control panel - in the old controller it wasn't turned on or off by the computer. Someday I may change this - for now I want to see if anything works. Vacuum stuff? Ditto. The Vacuum runs on compresed air and just has a switch on the front like the router. It was turned on and off manualy. If you look at the system now, without that motion control board, you have a standard 3 axis stepper system. You can choose to buss the enables for each drive together as one, or keep them separate, or for testing just jumper them. OK. Not sure what you mean here. What should I consider when making this choice? Are there limit or home switches? Remote control for the spindle? Speed? Vacuum platen/hold downs? Toolchanger? Unfortunately no for most of this. There is a switch for vacuum and for the router - but they are basic. I may be able to add a relay for this some time later. The next decision you're going to make is whether to use a motherboard/PCI parallel port for control, or go with an external pulse generator board (PPMC/Mesa/etc). I do have a PC with a parallel port and was planning on using that. I don't know what an external pulse generator board is? (or it that what I already have) Here is what I was planning on doing (is this the right approach?) : 1 - disconnect the cable from the board see: http://www.forsalesticker.com/bboard.jpg The one towards the left with the blue cable comming off. 2 - use a gender changer http://ecx.images-amazon.com/images/I/41RD21XB97L._SL500_AA300_.jpg to be able to connect my parallel cable to my computer and to the router. 3 - figure out which wires are step / direction and mark them as such in stepConf 4 - say a prayer 5 - repeat step 4 6 - turn emc on and see if my axis can move Regardless, make sure you get some form of breakout or opto-isolation board for protection. sorry. Now I need to ask the stupid questions - What is a breakout board or a opto-isolation board? What do they do? Do you have one you recommend?

Probably not if connecting direct to the parallel port. I do have a PC with a parallel port and was planning on using that. I don't know what an external pulse generator board is?

Something like this: http://cgi.ebay.co.uk/5-Axis-Breakout-Board-Stepper-Motor-Driver-CNC-Mill-/250847059324 (Though not necessarily that particular one). it converts the DB25 to individual terminals to make wiring easier, and uses opto-isolation so that faults in the drive electronics etc can't damage the parallel port. It will also tend to beef up the signals a bit. A typical p-port can source 5mA and sink 15mA, and that isn't very much. I have never bothered (the inputs to my stepper drives are opto-isolated internally) and just wired the drives direct to a DB25 socket. -- atp Torque wrenches are for the obedience of fools and the guidance of wise men -- All of the data generated in your IT infrastructure is seriously valuable.

Sorry for top replying. They are step/dir, so you can get rid of the interface board. Here is a data sheet http://www.servo-systems.com/pdf/ib10x_091803.pdf Pretty sure they just use a common L298 driver. No micro-stepping. 1.8 degrees per step is 200 in full step/400 in half step.

[Emc-users] stepConf configuration | EMC conversion
Andy - per your bottom assumption, and the fastest way to get things up and going: yes you'll probably want to remove the serial (if it truly is serial) to step-driver motion controller board from your system. The beauty is that the IB106's (although discontinued) are plain ol' stepper drivers, with step/direction/enable inputs, and are apparently capable of half- or full-step modes. The very first thing you need to do to make informed decisions is to get as many datasheets as you can; google will be your friend, (although since I had to go and drop by Schneider's website anyway), check out the PDF for the 106: http://www.imshome.com/downloads/datasheets/ib10x.pdf Don't stop there - if there are limit switches, get info on them. Spindle drive/controller, same thing. Vacuum stuff? Ditto. Practically everything in what you are doing is related only to being on or off - so don't let the electronics spook you. If you look at the system now, without that motion control board, you have a standard 3 axis stepper system. You can choose to buss the enables for each drive together as one, or keep them separate, or for testing just jumper them. You can most likely ( unless the datasheets indicate differently), use the default values from either conf or the stepper sample configs for testing with your hardware. Get one section going first, then add, then add, then add. Are there limit or home switches? Remote control for the spindle? Speed? Vacuum platen/hold downs? Toolchanger? -- Get the table motion going first, then add the remainder to the mix. Put the power for the stepper drivers/spindle on a powerstrip/switch SEPARATE from your computer - this is a temporary OMG e-stop until you get a real emergency stop system in place, that doesn't power off your computer. Keep that switch within reach. The next decision you're going to make is whether to use a motherboard/PCI parallel port for control, or go with an external pulse generator board (PPMC/Mesa/etc). For instant gratification, lowest budget, fastest time - if you have a PC available with a parallel port, I'd recommend that first. (again, start with simple knowns, add more stuff later) Regardless, make sure you get some form of breakout or opto-isolation board for protection. From here on in, you can pretty much follow any (or all) of the stepper-driven projects whether they be micromills or shopmates or anything else with steppers. There are plenty of projects in the wiki that you can learn from. The EMC Getting Started Guide includes pretty much a step-by-step recipe for stepper systems. As an aside, and Not To Be Recommended, but technically you can get a 3-axis stepper system running on only 7 wires (including ground) off the parallel port. More specific answers: driver variables - would actually depend a little more on experimentation given the mass/inertia in your system. Too quick on the pulses or too high an acceleration value and the motors may stall, or the drivers may not even sense it. Too long and the system will be sluggish. Since you have a router, which typically implies wood, you'll need to get your feedrates as high and consistent as possible so you don't burn tools. Leadscrew pitch - in stepconf it's looking for rev/inch (or if you prefer, TPI) - yes, you can count the number of threads per inch, (or in 10 inches, or in 100 inches - depends on what resolution you need) but don't forget to make sure you also include any gearing if it's applicable (there are other fields for that). You can always come back and edit/fine tune the scale values after the fact if necessary. Ted. = I got an old CNC router (phoenix) from a school district auction and am very eager to get it going.

Turn the leadscrew by hand and count the number of threads that vanish / appear at the edge of the stage for each turn: mark a thread, then watch it for one turn. If one thread vanishes / appears, then the leadscrew doesn't have a multiple-start thread.
