M2 upgraded to rev G (?) and requires new belt clamp
Posted: Fri Mar 19, 2021 7:50 pm
I think I performed due diligence and my question has not been answered elsewhere, although I find that surprising. So apologies if I didn't find the correct forum post elsewhere.
I have had my M2 since 2013. I have performed nearly every upgrade possible at this point, I think. My most recent upgrade today was for what I believe makes it a "rev G" machine. I have the aluminum plate that mounts to the x-axis belt and holds the hot end and now the print cooling fan. Not sure what this piece is officially called (mounting plate?). At any rate I installed this without issue, uploaded new firmware to reverse the extruder motor direction to accommodate the shift of the hot end from right to left of the extruder motor shaft. All seemed well. I went to print and heard grinding when the x-axis attempted to home. Turns out the striker on the belt clamp is too short to hit the x-axis limit switch.
I checked the MakerGear Github and there does not seem to be an appropriate belt clamp STL file with an extended striker. In fact I cannot find anyone else encountering this issue on the internet except for one other person who designed their own belt clamp with an extended striker. It is intended for an M2 dual with V4 hotend. I am printing that part now:

The only issue with this part is that although it has an extended striker which will hopefully hit my x-axis limit switch, I checked the mounting holes and they are off for the aluminum piece I just installed. Does MakerGear have an official part for this? I am surprised I am the first person to encounter this problem. Or am I missing some upgrade to move my x-axis limit switch? It seems like maybe this change was made for Rev G. The MakerGear rev G user guide shows the x-axis limit switch in a different position than mine is located (page 11):

Also now seeing this F/G cooling upgrade How To guide, but it doesn't mention anything about the x-axis limit switch:

What am I missing here? THanks!
