Mach4 General Discussion / Re: Upgrade Mach3 to Mach4 using smoothstepper and Machmotion I06?

Hi Jevs,

There is an old saying… “If it ain’t broke don’t fix it”

Basically, if Mach3 does all you want and it is working well then leave well alone. If, on the other hand, Mach3 falls short of your requirements then move on to Mach4.

Just my 2 cents

General Mach Discussion / Re: Machining relief problems

Hi Chuck,

Welcome.

Your Gcode and Mach3 set-up seems to run just fine here with a maximum Z depth of -5.848 mm in your test Gcode file. If your cutter is going deeper than that then two possibilities spring to mind...

1) Your cutter could be loose in the collet and it is moving during the cutting operation.
2) You could be loosing steps on the +Z axis moves - try reducing the Z axis Velocity and Acceleration (in Motor Tuning) by 50% and save the changes - does it still cut too deep ?

Another thought comes to mind - is your spindle motor tight in it's clamp ?

Yes it could be done where the work rotation is essentially a Rotary Axis.

Are you planning on Mach3 or Mach4 ?

1 question I am planning on using a stepper for the spindle ( Low rpm) and a y axis for the thread grinding. Is there a way to config mach that way. 1 time keep turning 2nd move proportionally to the z axis. ( the 2nd I can do with gcode easy enough).

I am not sure I fully understand this ?
