I think I would like to clear a few miss understandings here. I am not an engineer and will never be one. I am a furniture maker/designer with a keen interest in digital technologies and linux. I have built a 1.5m x 1.5m gantry style router table with high spec rails, carriages and bearings. It has been two years in the planning and taken 2-3 months to build in my spare time. I bought a CNC Kit from an online company in UK (who have not been able to sort my problem out) consisting of 3 x MSD542 micro controllers, 3 X FL86STH High torque Nema 34 Stepper motors and 2 X L6-PF11-001 (PS407) power supply units. The motors are connected in parallel with micro stepping set to 16 and the power at 4.2 amps. It has cost me well over £1000 and I would like to get it to work with a reasonable amount of accuracy.
I have tried using many settings of speed and acceleration but I always get a the same result. When engraving a line text the individual letters look okay but they are always misplaced along the y axis by between 5mm and 30mm, and always in the same direction. My question today is could this be because I have not used shielded cable to wire the powersupply and drivers together. If this could be the problem what kind of cable should I use. Or is there something else I should look into If any one can offer some advise I would be very grateful Cheers Aaron -- Powered by Outblaze ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
