I have purchased a A30Pro and so far have successfully printed a small cube. And that is it! I cannot figure out if it is essentially a scaled up A30 or if it is significantly different. Repetier looks awesome but it will not talk to my printer from a PC. ( I have tried two different PC hardware configurations and their associated USB ports) . Nothing works, there are no diagnostics and I don’t know how to move forward. I see there is a more recent firmware version on the web site but I don’t know if it is for my machine or if it is how to upload it without a working Repetier interface. Has anyone successfully navigated any of these hurdles?. I would appreciate any guidance.
Also the filament feeder is not very clever, it is hard to feed. Is it faulty or does it need adjustment?
