Last night My Pi Cubepro was printing ABS very well at 35 mm/sec, 230c, heated build chamber at 55c. "NO heated bed". Problem now is, it prints the part as a mirror image in the X-Axis, I need to change firmware and stepper motor cable tomorrow. I have CubeX frame and slides for parts, how hard is it to change to a Core X-Y? have you done it? Cheers Derekby hisforhack - General
Another Update. I re-installed the DRV8825 stepper drivers, set at 32 micro steps. I started to have problems with X-Axis shifting now! When I reduced the speed of the to 30 mm/sec the problem when away, at or above 50 mm/sec the X-Axis shifting appears. I am spoiled with the speed of my Delta 100 mm/sec plus all day long. Future plans I have order a Diode board for the X-Axis stepper driver, alby hisforhack - General
Hi to all I would to thank this forum and all the other forums that have been a wealth information on the conversion of my CubePro Duo. I have finally got my Cubepro Duo printing reasonably well, Everything is original except the Control board and LDC screen (MKS gen 1.4 & Smart LCD screen). I design two internal spool holders. I replaced the Chamber Thermistor with a 100 k Thermistor, Iby hisforhack - General
I will follow with interests. I have a Dead Rumba board. that will not connect with USB. This is my second Rumba board, the other one board had bad solder joints on the Stepper driver jumper pins. cheersby hisforhack - Controllers
Attached are the stl files for the two internal spool holders and filament guide The right spool holder is made up of two printed parts. two bearings, 2 washers, 3 nuts, threaded rod. (I printed 2 plastic bearing.) The left spool holder is fixed without bearings. Both spool holders bolt to internal frame with existing bolts. The Filament Lead (guide) bolt into holes left after removing the 3 cartby hisforhack - General

A quick update on the problem of the Y axis missed steps and shifting.(photo) My Pi Cube is Cubepro Duo Conversion with MKS GEN 1.4 MB, 5 DVR8825/A4988, Smart LCD Screen, MKS 28 LCD Touch screen. (Photo) I increased the ref V to the DVR8825 with no improvement. I Lubricated all the bearings and rods, I released some of tension on the Y axis belt. The Y axis appeared to move smoother but no improvby hisforhack - General
Hi to all I am new to this forum. I am in the process of converting my CubePro Duo with a MKS Gen 1.4 control board, using the original power supply, hotends,etc... the 2-Y axis steppers motor are run in parallel using a single DRV 8825 stepper drivers. I am having issues with Y-axis miss steps on my prints. The Refer voltage on all the stepper drives are set a .8 volts, I am considering increasiby hisforhack - General
