Reading them now. Looks interesting! Worth experimenting with to see if it really can detect a stall through current monitoring and then trip the...

These inverter parameters look interesting; PD118, PD119, PD120, PD121, PD122, PD123, PD124, PD125

Thanks pal That looks ideal for what I need I will have a close look at that. I just need to fit two rails and a rack and pinion to it.:beer:

dazza after trying loads of different remedies to the c beam twist on my cnc i ended up opting for the below from valder for my x axis....

Thanks in advance for your insights!

Episode 2, just making it better all round . . .

Maybe but I've not found it in the 'documentation'. Would simplify things if it did.

Are you actually seeing backlash on your pulleys ? it's not something I've noticed or thought much about. Edit: I've just seen the older post by...

Best of luck with your project, it might be a long road but will be worth it.

I would exxpect the VFD to have a motor stall function in it's parameters, the ABB one I use certainly has although I have not tested it in practice.

I always found that anything less than 5um per step made things a bit slow when it came to the rapids, but I assume stepper technology has moved on...

Dean (jazzcnc) builds machines. He is near Prontifrack

The issue with microstepping, is that you're essentially relying on the energised coils to balance the rotor between steps, so any external forces...

I use similar figures with a lathe cross slide—5um per full step and 2.5um per half step to give 5um on diameter. I found that measuring with a 1/10...

I know this has been a long time. My Clock Club has just been donated one of these engravers. I was wondering if you still had access to the...

Brilliant. I've just tested the input/output triggers, and thanks to you, Voyager, I've got it working. I will look at the disabled push button...

Thanks mc It does need to be c-beam really, if i have no choice then i,ll have to have a rethink but i'm sure i saw big stuff somewhere, a while...

I did have a list of with some UK suppliers from when I was looking at building a router, but I can't find it. Only thing I can find, is the model I...

3D bas-relief portraits for badge manufacturing. J.R.R. Tolkien, Salvador Dali, Joseph Brodsky, Kurt Cobain, Bob Marley, Steve Jobs.

Thanks for this. I think you are correct. My Z axis was near the limit of its travel and the steel used for the part is gauge plate. The part is...

Hard to be certain on the info provided but my first thought would be backlash and flex in the mechanical system, rather than CAM setup. Backlash...
