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...

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...

you can also use the input output triggers to disable the spindle pushbutton relay for safety so you cant eject the tool during cutting ,,,enter the...

Ahhh that's great, thanks for that. I'm on Holiday at the minute but I'll give that a go when I'm back, thank you

hi phil just seen your message ,havent been on for a while ,,if you goto settings , i/o trigger , output trigger ,enter your input port and pin...

Hello I'm from near bath what help do you need lathe or mill plus control software you are using I'm a skilled machinst

Mine was rather extreme too: I ended up making my own pulley, as it seems that many of the pulley suppliers make their pulleys from the same...
