![]() ![]() When we do the Rambo conversion we will likely switch to an LCD, heated bed system and power supply from Lulzbot.įor others following I will say the CubeX linear motion, extruder and frame hardware are worth some money. ![]() We have also removed the the second extruder from the carriage to reduce mass and it does seem to position much smoother. ![]() However, we never push the print speeds very hard as we are more interested in accuracy. We feed it from the top while the spools ride on some custom holders we printed. We are running 1.75mm Pro ABS from Matter Hackers without any issues. Interior cabinet temp runs about 80-90 degrees F when both printers are running for several hours. We have two of these printers and they are both stuffed in a custom cabinet that runs it's own fans to circulate air and keep cold drafts off the part. PLA is not an option once you make this change. All the big fans on the carriage have been reversed to cool the extruder motors and not blow directly on the part. Temp measured with a Fluke IR thermometer at 120 for first layer and ~110 for rest. We print ABS on glass with purple glue stick from Elmers. We are using heated beds based on the Mk1 PCB, but it's all manual control with a variable voltage external power supply. Really just waiting for a hardware failure to motivate me to make the change. Right now we are having OK luck with the stock hardware running Kisslicer/CubeIt. I hope to get back to this project in the next few months. ![]()
