![]() I replaced the defected LED lighting with two 12v units connected in series for 24V I replaced the Chamber Thermistor with a 100 k Thermistor, 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 would to thank this forum and all the other forums that have been a wealth information on the conversion of my CubePro Duo. After some more testing I will be looking into upgrading to a "Rumba Board" so can set up the second extruded. Now the problem is that I can only use one extruder. #CUBE PRO DUO DRIVER#I wired the two Y axis stepper motors separately and used the Y axis A4925 stepper driver and 01 Extruder A4925 stepper driver to drive the each Y axis motors. There was not improvement of the Y axis shifting (Photo) I replaced the 5 DVR8825 with 5 A4988 stepper motor drivers. The Y axis appeared to move smoother but no improvement in the miss step on the Y axis. I Lubricated all the bearings and rods, I released some of tension on the Y axis belt. I increased the ref V to the DVR8825 with no improvement. My Pi Cube is Cubepro Duo Conversion with MKS GEN 1.4 MB, 5 DVR8825/A4988, Smart LCD Screen, MKS 28 LCD Touch screen. #CUBE PRO DUO UPDATE#I haven t started yet but will very soon and really get my head around it.Ī quick update on the problem of the Y axis missed steps and shifting.(photo) I think the bearnings need to stay there but a whole redsign of the head is on the cards. Personally I think the filament path and length was a little crazy, but that's just me. Yes I plan on taking the spools out of there. The way the extruder mount is designed, with the hot end located between the massive X axis bearings, makes it very hard to see what's going on at the extruder nozzle(s). I have almost given up on them and will be replacing them at some point soon. The extruders that come with the machine are not especially good- they seem to have a large heated volume that oozes filament constantly. It should be pretty easy to move the bed plate over on the existing platform, but if you're going to heat it you'll lose some Z volume because you'll have to stand the bed plate up off the support plate. The bed is shifted to one side to make room for 2 filament spools on one side of the machine (and one spool on the other side). ![]()
