JG Aurora Z-603S Owners

weird one, these are such good machines, been running for years without issue. After a print today I happened to notice that the Y axis has got incredibly 'stiff' and when steppers are disabled, or machine off, it takes a huge amount of force to move it. Put a little grease on the bearing rods but no different. Any ideas? should i strip and replace bearings? thanks for any suggestions

My heated bed no longer heats up. I've tried replacing the thermistor on it with no success. This tells me one of two things (1) it's something in the bed and it should be replaced. (2) The PCB with the circuit for the bed thermistor is fried and the PCB needs repalcing.

I'm trying to troubleshoot this in my spare time so if anyone has ideas, I would appreciate it. This is my ABS printer as it is highlysuccessful with ABS (I have plexiglass cover all around this guy and need to get it working again soon.

Hi, has anyone considered upgrading to Trinamic drivers such as the TMC2100 or TMC2130 ?

The thing is the drivers are not removable so I'm thinking of getting a new RAMPS board.

Please let me know !

I returned the first one and got a replacement unit, same thing. I switched between 4 different raspberry Pi units. Same thing. Octoprint sees the USB port, but it can't negotiate a connection speed -- cycles through all of them and then fails.

Does anyone have a solution to this?

Does anyone know which replacement nozzles and heatblocks are compatible with the jg aurora Z603S?
