Hello,
I'm trying to print X carriage and X end for my Prusa i3 printer. I bought a kit from MakerFarm and it uses laser cut wood instead of printed parts, except for the extruder.
I did not like the fact that the extruder motor is protruded far to the front (away from X rods), which amplifies the vibration of the extruder and hot end, especially when printing honeycomb infill pattern.
So, I printed a modified version of the extruder, one that puts the motor directly above the X rods: [www.thingiverse.com]
Looking at the new extruder, I realized that it can be mounted to the X carriage with a couple of screws side way - I can only mount the extruder on my wooden carriage using the screws fro the bottom - and I really liked that, too. This means I won't have to lift up my printer, lay it down with its back to the ground to expose the bottom of the X carriage, in order to detach the hot end and/or extruder.
In order to use this side screw holes, I wanted to print the X carriage. Colin from MakerFarm advised me that it would be a good idea for me to print the matching X idler and X motor, in case the X rod alignment/cap is slightly off between the printed X carriage and original/wooden X ends.
So, I downloaded the SCAD files from github: [github.com]
I was going through the Configuration file and changing some values here and there (but not that much, I think all the parts in my MakerFarm printer is pretty "standard"). However, I am not sure what the correct values are for the following:
Actually, I have confirmed with Colin that the tooth distance for my GT2 belt is 2 mm. And I guess the tooth ratio is supposed to be 0.5 because that was the value specified for GT2 belt in the configuration file.
But, what about the belt thickness? There's a comment in the configuration file saying " For T type belts you will probably want 0.8mm or so". Well, what exactly is "T type" belt? Is GT2 one of the T types, since it has T in its name???
I measured the thickness myself using the caliper (the thickest part, in other words from flat to the top of the teeth), and it's about 1.5 mm. Should I just leave it as 1.75?
