Re: Older Shopbot desktop build
The power supply is 48V as you remember. 6.7A I believe those Haydon Kerk motors draw 2 amps, so 6.7A on the PS should be good I will look into limit switch upgrades. Should be plenty of choices but if you have a known accurate/reliable recommendation I welcome it. I prefer proximity sensors. I wou...

Re: Older Shopbot desktop build
Your project is more than doable. I have done a small format drilling machine with that exact combo and would suggest, that since you don't need, and therefore don't need to pay for, all of the IO features on the MX-4660. I would recommend the LeadShine DM-542E at $35 each ($140 total) rather than t...

Re: Losing connection with open loop steppers.
What voltage is the power supply for the drives?
Set your step pulse to 100khtz. Those drives are not 200k

Re: 2006 ShopBot PRT Alpha controller upgrade...
Gene... In theory what you wish to do is possible, but in reality, very difficult for the inexperienced. Here are the reasons: 1) Without gear reduction you would have a 0.318.. turns ratio. Far below what is required for Centroid. That direct drive alpha was so bad that SB traded them out for gearm...
