Hi Nick,
Yes, I did adjust the side screws with out the spindle motor, clamping it by hand force like recommended. I think the problem might be that either the ways or the gib is not ground right. Now it works, but running a program you can hear an emerging vibration when the spindle is really low on the axis. It can bind at random. I just went through a long program getting ready to jump in a lower the feed if needed. I had a few problem with the Y binding as well. The nasty thing is that it is not easy to get the off set back again as I only have soft limits which depend on the machine coordinates.
I tought I could use the Taig to free up my Bridge port and keep both running in the same time. It appears the Taig is too time consuming as I have to watch it all the time, or lose offsets all the time.
The control is from Deepgrove in NYC. The steppers are 253 Oz and the program is Mach 2.
Thanks for all you help!
Andy

Have you played with the shoes on the side of the z-axis that clamps it to the slide back to front? You may find you need to adjust those as well.
What controller are you using? The Taig one or an aftermarket controller?
What are your rapid speeds set at? |
