Serial Machining error

Message par othersounds le Dim 21 Avr 2013, 21:44

Hello,
I have a weird problem when i do a serial machining using the galaad serial machining option.
Every time it mills a copy of the object the Z's cero gests a little bit deeper ...
I see it very easily because the traces of the contour being cut in the cnc's bed (martyre in french) gets deeper and deeper from the original to the last ...
Of course i do a surfacing of the cnc's bed every while and then, that can't be the issue ...
I'm using Galaad with a CNC-Step S-720 with Axemotion PulseBox-1

Does any one fo you have experienced this?

Best,
Felix

Strange
Could be hardware problem:
Could be so that your Z stepper is a bit overloaded and misses some steps every time it tries goes up but never when it goes down (heavier to lift than to lower)

Try to run like 10-20 drillings side by side at full speed (in the air, no need to actualy machine something). Measure Z height before and after to see if this is the problem.
Look at your tool setting so that Z plunge is not slower with just that tool, just to make sure you get the full speed...

If you actually lose steps you need to lower the speed or accceleration of your machine.

There's a setting to to run an axis "zeroing" after every machining, this way Galaad will tell you if you lost some steps.
