Re: Z not lifting when printing - 11 years ago
OK, Thanks guys. Started changing VREFS, Set them around 0.4 and motors started getting hot. Set them lower and started acting erratic and growling around. Ended up with X @ 0.443, Y @ 0.500, Z @ 0.800 with the two motors, Now I think all I might have to do is get the Z steps per unit in Marlin set. Z just doesn't seem to want to lift the right way as of yet. Thanks for teaching this old doby FarmerChuck - General Mendel Topics

Thanks for the reply, It doesn't or hasnt run long enough to overheat, VREF's are set at X=0.550v, Y=0.621v, Z=0.542v, E0=0.575v. It does it right off the batt. When hooked up to Pronterface all the axis work fine its just when I try to print that things go haywire. For an example it's like drawing a circle then moving down the Y axis about half way from the center of the first circle and drawinby FarmerChuck - General Mendel Topics

Hi, I'm having a little trouble setting up my Wades extruder and was wondering if you have yours set up for 16 steps (all the jumpers installed). I've tried to find out which steps I should use with the Wades but have not found anything about it in the forum. Just to set the extruder up for 8 steps in the general setup using a direct drive stepper motor.by FarmerChuck - Firmware - mainstream and related support

Multiple fan connections - 11 years ago
Hello, I am just getting started with 3d printing & have been getting my materials & parts all lined out for a printer. I have the Sainsmart mega 2560 R3 with the ramps 1.4 with the A4988 drivers & the 12864 LCD. The question that I have is if I have one fan running to keep my ramps cool upon start up connected to the D9 terminals on the ramps where do I hook up another fan that I canby FarmerChuck - RAMPS Electronics
