General Mach Discussion / Re: Limit switch wiring
« on: January 01, 2016, 03:59:17 AM »
If I were doing it, I would run a separate wire to each switch, ground each shield in my cabinet and make the series connection in the cabinet.

Slightly more wire but easier to fault find i think?

I have a row of DIN connectors with the series connections made on the panel side, all my inputs and outputs just go to their own connector terminals which are all numbered and shown on a sketch.

Ok thanks

but the overall effect of steps per and acceleration / speed should remain the same no?

General Mach Discussion / Kernel speed change
« on: December 31, 2015, 01:05:58 PM »
Hi all


does changing the Kernel speed upset or affect any other settings???

I have to replace the pc on my plasma table tomorrow and was wondering if it was also a good time to reduce kernel speed as I am fairly certain its too high.

Currently on 35khz was thinking of dropping to 25khz.

Won't bother if it upsets anything else as i really don't want to retune everything.

I think i would do that as well.

What sort of machine?

My plasma just kills the torch, stops all motion and goes into E-stop mode if a limit is tripped while running.

Are you 100% sure BOTH motors are actually turning under power?

I had a similar issue when building and the gantry was being pulled along by one side which would then cause the other side to spring forwards every few inches, sort of like how you explain it.

I would pull both motors and set them side by side on top of the table, fit a marker - tape or pointer etc to each one and run some sync tests.

Then failing it being a mechanical issue, to rule that out pull the motors of and make sure the axis slides freely on its own, i cant really offer much more up here, hopefully someone will chime in.

Are both drives programmed exactly the same on the dip-switches, assuming they have them??

Are both motors identical?

Are you 100% certain both motors are tuned exactly the same - speed, acceleration and steps per???

If yes it sounds like one side is losing steps.
