We don't have 1/32, most of us. :) Then again, I'm not sure it's really necessary. The positioning precision does not increase, really, and 1/16 is already quite smooth, so 1/32 may be overkill. Also, 1/32 needs twice as many step pulses as 1/16, so if pulse frequency is the limiting factor, 1/32 will make your machine slower.

Thanks for the info. 1/16 it is then. I think I have just about all of the mechanical stuff finished. Seems like everything is pretty solid. Going to start the wiring process in the next day or so. I purchased a lot of molex connectors from Mouser and a crimp tool from pololu. I am definitely going to need some help on the math after I get done with the wiring.

One thing I do need is some extra M4 t-nuts that fit the makerslide. Does anyone have a source? I checked inventables but they only have M3 & M5.

The vertical play is of no consequence -- gravity gives you enough preload to avoid backlash from that.


Can you post a link to latest design, I was too busy the past few months and I missed this

I finally got everything together and miraculously almost everything seems to work as it should (motors, heaters, stops). A run down on my setup:

RepRapDiscount mechanicals kit
X3 controller
Repetier firmware
Repetier Host software
Helios heated bed
Wade's Reloaded Extruder
E3D hotend with .4mm nozzle
30A switched power supply
Macbook Pro laptop


One issue I thought I could fix is that I can't get the hotend to heat above 270C. In the E3D instructions it says to heat the hotend up to 300C and then tighten the nozzle onto the heater block. For whatever reason, my hotend gets to 270C and then cools down to about 260C and then cycles between the two. I found this line in repeater firmware and changed it from the default 270 to 310C thinking that would fix it.

#define UI_SET_MAX_EXTRUDER_TEMP 310


Restarted the X3 but same problem not getting above 270. Any ideas on that one.

The only other issue is that when I home the y-axis it hits the stop and seems to reverse itself for about 20mm or so.

I still need to level the bed, put some kapton tape on the glass and give it a go.

Sorry for the silly question, but after you changed that line, did you compile the firmware and upload it to the controller?

Not silly at all. That would be something I would easily forget but this time I did infact recompile, upload and restart the X3. I was wondering if there is another place in one of the many files that make up the repetier firmware that defines the max extruder temp.

I will try it again tonight to see if it didn't take the first time. I am pretty stoked that I was able to make just about everything work on the first try.

Thanks Flickerfly. Your firmware file was spot on for me. Can't wait to try and print something later this week!
