The printer is prone to break and slip because the design uses thin wire to move the carriages up and down. I'd like to convert my printer over to using a belt like the one on this page, but the conversion kit is no longer available. I believe I can 3D print the carriages, but would anyone be able to point me toward the resources to convert my printer over to using a toothed belt?
Contact Brian or Lykle. We all have Boots Industries printers and have heavily modified it to belt drive and magnetic effectors. The print quality has improved drastically. The old Boots support group has since moved on to Slack and we are in constant contact everyday.
