I'm looking for an easy to source set of metal drive gears for a Greg's / Wade's style extruder. I've been searching for a 4:1 helical gear set, but the one's I've found so far (RC car parts) are too small for a 5mm motor shaft and 8mm hobbed bolt. I'm set up with a PLA set of herringbone gears and I think the PLA isn't going to handle my motor temps. Not extruding yet, but I have my machine inby Dirty Steve - Mechanics
I'm getting my printer up and running. I have 5.1v 1.0a motors running on a 4 Axis TB6560 board with Mach3, PSU power supply. Have motor drivers set to 50% current, on 25% current the motors barely have any holding torque. I have tuned the motor drivers in Mach3 to where the motors run smoothly without jerking or missing steps. I've been running pen plots to do tests and calibration, 2 hoursby Dirty Steve - Controllers
Up and running!!!! (for the most part.....) Here is a pic of one of my first successful full gcode program run, with pen attachment. Dialing in and calibrating, just waiting for hot end temperature controller to arrive. Going with a 120v hot end with a cartridge heater. How do you get pics to display in the body of a post? I've seen images displayed this way on a few posts. Motors are HOT! Puby Dirty Steve - General Mendel Topics
Made with oak. Will insulate the underside of the X carriage with thin automotive heat shielding. Motors are spaced off the wood with rubber isolation washers.by Dirty Steve - General Mendel Topics
Here are a couple of pics for my wood based Mendel I have named Gepetto, with Z axis extended base pieces. Ready for electronics and hot bits. Going to go with a 4-axis TB6560 controller and Mach3 (already researched mods to opto isolators) and a variation of a Wildseyed simple hot end. Once I get it up and going the first mods are going to be belt guide Idler pulleys for the X and Y belts, alreby Dirty Steve - General Mendel Topics
