In motor tuning with acceleration at 10 what velocity do your motors stall at ? (what is the maximum speed you can achieve ?)

My stepper motor output from the drivers to the motors is shielded and bonded to the equipment ground.  My control wires from the interface card and stepper drivers are bonded to each other.

Are your limit switches wired with shielded cable ?
Are those shields bonded at the controller end only ?
Are your stepper motor cables bonded at the controller end only ?

Hit reset and use the m03 s ********* relay clicks led comes on, m04 relay clicks led stays lit and it wont respond.

Should you not be using M05 to turn the relay off ?
Under spindle setup have you reduced the spin up / down delays ?

You need to track down the problem of lost steps, G28.1 is no solution.
Is your stepper motor and switch wiring shielded and is the shield connected to ground at the controller end only ?

Could it be the 360 deg roll-over ?

Hi Nuvarian,

Welcome to the forum.

Could be that you are set up in metric units and the GCode is in imperial units or visa versa.
Check the GCode for G20 or G21 codes - this could be a clue.

Maybe a good idea to check earth continuity and correct polarity of live / neutral on that extension cable then  ;)

Hi Dan,

The fact that everything was working OK for so long but now it does not work indicates, to me, that something has changed.

Have you made any changes to your installation ?
Have the power company ripped out your earth stake ?
Etc. Etc.

Something has changed, think hard, what have you repaired ?  ;D
