Hey all,
Having a hard time getting things up and running on an Azteeg X5 Mini with SD5984 stepper drivers. Veered away from spending $400 on an upgrade path through the printer manufacturer after seeing how great smoothieware was and decided to take the plunge into adapting my printer to run off this. Totally up to learn the ins and outs of smoothieware so I can self service myself and help others but would really appreciate any expertise others can offer to get my printer up and running again
My issues
100mm step moves more like 400 steps in Y axis
What I have tried/observed
-the creators of my printer got the values im currently using in my config file from the leadscrew design and timing belts etc, things im not to sure about so I figured these would not change between Marlin and Smoothie
What I think is happening
-my steps per mm are wrong not exacly sure how to figure this out
-pretty sure this must be tailored to your printer and cant be left as default
-smoothieware doesnt know the size of my bed, I may not be reflecting it correctly in firmware
End stops not bouncing back after contact
What I have tried/observed
-the direction in which the steppers move is correct as they move toward the limit switches and make contact now
-when they make contact they bounce back and move right back to the limit switch keeping it compressed
What I think is happening
-because my steps per mm are not correct after contact is made the steppers do not rotate enough to stop compressing the limit switch
Z axis is not moving no matter what im setting the current to
What I have tried/observed
-it would initially move for a few steps then it would stop, now no matter what I set the current to they dont move
-changed between 0.5 to 2.0 amps using digipot
-reviewed the config file to turn down acceleration and anything else that might be playing a factor in how quickly this moves
What I think might be happening
-because my bed dimensions are not being correctly reflected when i send a command through pronterface for a step size of 1 in Z axis its trying to move 20 steps really quickly
