Hi All, cool to find this group on my printer so long after I bought it.
My "2.5up" looks mostly like a standard 2up but it has a second Z-axis motor to lift the opposite end and behind the lateral head axis. I also replaced the controller A fastbot BBP 1s. It has a built in server so it's just an Ethernet device on my network. It has the stone heated bed. I put in mechanical limit switches.
I ran a few tests and found one issue. Because all the movement torque is applied along only one edge of the table, it torques/twists then relaxes. It happens every step of the stepper motor.
So I want to run a shaft extension across to the other side of the platform and add a second belt so both sides are pulled at the same time.
So here is my dilemma... I can't find a new 12 tooth 5mm bore 3mm pitch [I think 3mm is what it uses] timing pulley. Does the original manufacturer still even exist? Or a source for one?
Anyone out there ever change out the pulleys on their machine for a different one and have one from the original they'd like to sell me?
Thanks folks!
Bill
