Hi, folks. After a long hiatus from my 3d printer issues I've decided to continue with my CubeX Trio. I need to go out for a while, but there are a bunch of older threads and posts for the CubeX printers. Mine is working with one extruder and the Rumba+. I'll post my stuff and/or links later today. I dumped all three factory extruders and machined some J6 hardware to fit the original carriageby TJM3D - Reprappers
Well, I have some time again to fool around with this beast. I have three J-heads machined and installed and still only one working. Physically they all work. Just needed to update the firmware, which I still haven't done. Picked up a Diamond tri-color hot end that looks interesting so very soon I'll remove the custom machined J-heads, heaters, etc and mount the Diamond triple hot end and Bowby TJM3D - Reprappers
Just happened to check in and found this. I haven't done anything with mine for months but I'm about to restart this project. Were you able to find the problem with the re-flash? If it compiled I'll make a guess that the communication with the board wasn't right, maybe a USB cable that was too long.by TJM3D - Reprappers
Yup, lots of work, but most of what I hoped to gain was exactly that, learning the 3D machinery, and the thing prints OK, too. Plus, the local community college has three of these, four counting another personally owned unit, in non-working condition and I'm trying to get a short 3D hardware maintenance class approved specifically to get these machines working again by converting to open source.by TJM3D - Reprappers
Doesn't appear to be much interest in these CubeX printers any longer with printer prices dropping significantly. Anyway, parts for a another mod are on the way for mine. I'm gonna remove the two Y-axis steppers and use one double shaft 23 (same as the Z-stepper in this printer) to drive the Yaxis. Centered and mounted between the left and right sides and shaft driven from each side of the 23by TJM3D - Reprappers
Here are some pics of my second print using one extruder. It's the 20mm test cube shown from the top and the side. My diagnostics for setting the firmware numbers is lacking so I'd like to get some input about how this looks and what to change to make it better. From the top the print looks a bit rough but better than some others I've seen posted. Looks like it needs more extrusion, but I doby TJM3D - Reprappers
Update. The thing actually works. Details, and pics later, if there is interest. I tried to use as much of the already routed wiring which worked out nicely. More to do to make it look nice. I constructed a small circuit board with headers to accept the stock connectors from the CubeX board with connections to standard pin headers then link to the RUMBA pin headers with short custom wiring. Iby TJM3D - Reprappers
Thanks. Only does it when using the LCD input for movement. If I connect and use Repetier for manual control or feed some G-code for movement all three axis move without the short delay. Did a dry run of a small part (there's no extruders in the printer yet) and the movement appeared normal and smooth. It'll be a week or so before a real test can be run. tjmby TJM3D - Controllers
I think this is the correct forum. Move it if necessary, please. I have this RUMBA board connected and operating the steppers with 8825 drivers and it appears to be working almost normally but let me describe the problem. First, Zaxis is a 23, Xaxis is one 17 and the Yaxis is two 17s wired in series. I found that when operating the steppers with the Smart Control panel only the Y axis occasioby TJM3D - Controllers
Thought about getting an account, saw this thread, scratch, post to my own sites. thanks.by TJM3D - General
Problem found. Cheapo 1M stepper driver to stepper extensions wired incorrectly, at least for my purposes. swapped a couple of the pins, now operates smoothly, accurately and quietly. Easy fix.by TJM3D - Reprappers
I know, I know. The 8825 doesn't play well with the Rumba, or so I've heard. But I have them and once I work out the details, I'll likely convert to something else. BUT. The first problem. Loaded some software for the Rumba and full graphic smart, mounted the drivers adjusted low then moved the voltage up, .5v to 1.6v, a little at a time. Using the controller, I'm trying to move the steppersby TJM3D - Reprappers
Hey, thanks for the info. Good write up.by TJM3D - Reprappers
Wow! Lot of stuff to browse. I'll get to it eventually as I go through the posts, but did you rewire the Y's serially, and if you did can you point me to the post number for a quick look at how you did it. I have my own idea worked out but I usually find a glitch or two in my designs after viewing other designs. I'll be using a RUMBA, 8825s and a 24V power supply for mine, all subject to chaby TJM3D - Reprappers
I've found some conversion information about redoing these things with several different boards but the reports are incomplete as to how multiple steppers are wired for any particular axis. This cubeX has two steppers for the Y travel and I've already come to the conclusion that wiring them in series is the way to go. I have a pretty good idea of how to do this but if there is some schematics/dby TJM3D - Reprappers
