I'll check them out. I do have a new cable on order, I may just swap it out and see if it changes it.

I'll check them out. I do have a new cable on order, I may just swap it out and see if it changes it.
They are dmm encoder cables for the dyn4 drive. Kinda a metal oblong on the drive side and a plastic clip on the motor side. I have tried ferrite cores on the encoder cables, didn't see much of a...
It could still be, thats why I want find some data logger and at least know for sure on the voltage side. Without the torch running the machine moves great, sounds great etc, nice and smooth. The...
Ok, finally talked with the DMM tech and we started suspecting voltage fluctuations upstream of the plasma when under load. So of course today when I go to monitor the voltage of the generated 3rd...
Yes, one 3 phase feed to machine. I have a line reactor before the power for the drives. And recently tried adding small transformers to the logic power for the 2 gantry drives as DMM recommended as...
I have a plasma table with dmm servos and dyn 4 drives, has a dual motor gantry for Y axis. Built about 4 years ago, worked great until recently when using 65 and 85 amp tips to cut thicker steel one...
Control has been great, the guys in Australia are great to talk to. I have a few little bugs in my system yet, but they were/are working with me to find them, mostly I just havent had the time to...
Oh and I went with an Icon Control 6 axis , planning on modding back gage to independent moving fingers in near future. I got it from these guys. But installed it myself.

It's running, everything works like it should, some could be better just need more time tweaking. I don't have any of the old stuff anymore.
It would probably be easier to buy a control kit with...
Got the spindle tube all machined today. Just have to make a nut for it now.

Got the spindle tube welded to the back plate and machined to fit the chuck. Decided to machine the tube while attached to the chuck so as to be sure everything is perfect alignment. Hopefully...
Got the bearing flanges machined. Still have to tap and countersink them for flat head screws yet then they will be done. Then have to design up a timing belt pulley and whenever the tube for the...
Got most of the machining done on the main frame, still have to punch the holes for the jackshaft but first have to figure out where that will be more exactly.
Should be able to machine up the...
Got a bit of welding done on the rotary frame as well as the chuck backplate. Need to order some tubing Monday for the spindle. Now I can start machining the frame for the bearing hole and mounting...
Started working on the rotary axis for the plasma table today. Got all the big pieces cut, lots of welding and machining to do now....
Is there a way to adjust the zero speed point on the dyn4 drive when running analog command speed servo?
I have 2 servos with brakes and 2 dyn4 drives, being controlled by a +/- 10vdc analog...
I have some build threads on other forums. Welding Web being one
Got some 1/2" plate cut on the plasma tonight. Log grapple, gussets, and outrigger parts for my log trailer build, and a barrel lifter I found online. 1200 ipm rapids on X and Y now.

Ok, good to know.
I was trying to look up info on some servos and drives I'll be needing for a project and I can't get their website to load at all. Anybody else have this problem, or did they fold up or what?

The tech told me the Indexing card is for development use only and it wouldn't handle a lcd and all it does it run through a pre programmed set of moves one after the other.
I found this article...
Hmm, I'll ask the tech I've been talking with about it. Might work, says 8 bit external position trigger. I'm wondering how I can enter a dimension and have it goto. Could be it only steps through a...
Have not seen that, got a link? Only board I saw on their site was a mach3 breakout board, I don't want to have to have a PC to run it. The Dmm tech guy I've been talking to says the arduino route...
I've been told I can do a simple point to point motion control system (1 axis) using the rs232 command into the dyn4 drive from an arduino micro controller. Has anyone here done this? It looks like...
Yeah, I have sheetcam and it was a combination of overburn and pierce delay. I'm not positive but maybe the longer torch lead (35') needs an extra .1 sec for pierce than book specs, seemed like it...
Well, Finally made some paying parts today. Still a few bugs to work out but I was pretty happy. Even learned how to do nesting in Sheetcam and everything.

Well, I got the Ohmic sensor installed this morning and working. Here are a few test shape coupons I cut, playing with accel rate and probably need to check my axis for backlash somehow and see if I...
After changing the step/dir logic power supply from the drives to the controller the drift stopped. I also shielded the step/dir signal cables to the drives.
Actually got a couple test shapes...
Ok, so I moved the servo motor and drive ground connections over to the table ground. Still had the drift issue.
I pulled the step/dir breakout board and mach3 ubob board out of the cabinet as far...
