Hi guys, great forum. I’ve done a bit of 3D printing and drawing but I’m new to CNC. I have been playing with Mach 3 demo for a while and now plan to convert my LAGUN FU-1 LA Mill to CNC using one of those £350 eBay kits with Nema 34 1600oz steppers. My machine has really good tight beds but some backlash on the lead screws with 0.008” on the X , 0.0001” Y and 0.004” on the Z. I can adjust the X down to 0.005” but with a noticeable stiffening on the hand wheel. Being a knee mill the Z moves the entire bed and therefore takes 9.5 lbs feet torque to get moving up but the X & Y are below 1 lb ft to start moving, so can I use say Nema 23’s 1200 on the X&Y with a 34 on the Z?
Can you mix motors sizes on one break out board with different drivers and power supplies?
Has anyone converted a Lagun machine?
So many questions, am a wasting my time with these eBay jobs? http://www.ebay.co.uk/itm/1517158967...%3AMEBIDX%3AIT
It’s for hobby use only and my main interest is motorbike parts etc so it only gets infrequent light use.
