General Mach Discussion / Sable-2015 Cuts Small

« on: April 26, 2013, 11:07:56 PM »

Hello, I am having some trouble getting my CNC Machine (Sable-2015) I purchased around 2 years ago and now have sometime to play around with it. The trouble I am having is when I load a G-Code into Mach 3 and perform a Cycle Start. The motors start moving but the size of the project is small and is not sized right. I have been searching and trying different settings in Mach 3 but haven't gotten very far. The CNC machine is attached to a 3Axis+1-8435 Stepping Motor Drive -> LPT port on a desktop running Windows XP. Here is my Mach 3 settings.

Native Units: MM
Kernel Speed: 35000Hz
Motor Outputs:
X Axis: Step Pin# 2, Dir Pin # 3, Step Low: Enabled
Y Axis: Step Pin# 4, Dir Pin # 5, Step Low: Enabled
Z Axis: Step Pin# 6, Dir Pin # 7, Step Low: Enabled
Output Singnals:
Enable1: Port # 1, Pin # 14, Active Low: Enabled
Enable2: Port # 1, Pin # 8, Active Low: Enabled
Enable3: Port # 1, Pin # 9, Active Low: Enabled
Motor Tuning and Setup:
X Axis: Steps per: 533.333, Velocity: 799.8, Acceleration: 150, Step Pulse: 1, Dir Pulse: 1
Y Axis: Steps per: 533.333, Velocity: 799.8, Acceleration: 150, Step Pulse: 1, Dir Pulse: 1
Z Axis: Steps per: 533.333, Velocity: 799.8, Acceleration: 100, Step Pulse: 1, Dir Pulse: 1

Also on the controller board itself the excitation Mode is set to W1-2 Phase. I have tried 2 Phase Excitation mode which does seem to size the cut right but the motors seem to move to fast and lock up.

Any Help would be nice, Thanks...
