Hi all,
I have a problem that I think is firmware, but I have run out of ideas.
I've had a CTC Cartesian with a Geeetech GT2560 Rev A board for a couple of years which I have updated slowly over time, including a home built X5 extruder gearbox, To use this I have been setting the flow rate to 500%.
I have decided to fit lead screws which I could not see an easy way to adjust for in software, so I have decided to reflash the board. After finally getting the board to reliably go into a programming mode I have updated the firmware using Marlin 1.1.9 and Arduino IDE 1.8.5. Now I have as strange problem.
Using the discount smart controller board I can move the print head around with no problem, but when I try to print any file the printer will home on all 3 axis no problem (G28), but as the head tries to move up 15mm (G1 Z15.0 F600) the Z axis will move a small amount (30-45deg) and then buzzes, the fact that it moves around using the controller is confusing me on where the problem lies.
So far I have:
Changed the A9844 stepper controllers around.
Rewritten config files with different Z axis speed and acceleration, double checked pins_GT2560_REV_A.h match pins on board
Hand written Gcode file just to move head with G0 and G1
Extracted from originally d/loaded Marlin zip file, this file has been used you update the firmware on a custom build cube with no problems
Compiled on 2 different computers
Any thoughts would be useful
