Pulse XE Y-Axis Linear Rail Guide Upgrade

Pulse XE Y-Axis Linear Rail Guide Upgrade

The MatterHackers Pulse XE is a MK3S+ clone, however not an exact copy, some parts or combination of parts are of different size and manufacture.

Based mostly on version 2 of KalleKnall's Prusa mod. I tried several of the existing linear rail mods, none which worked for the Pulse XE. 

I highly recommend upgrading the mainboard on the Pulse XE to Duet 3D. It will change the printer and make it a serious beat. Extremely reliable.  

Rear mount [Left and Right] hole size increased to 4mm since only one bolt holds it on the printer. All of the Y axis mods are this way. You can use up to a 6mm bolt if you wish, just drill out the rear mounts and add T nuts that are threaded for that bolt size!

Also the Rear mounts use T-nuts instead of nylocks. This keeps the nut from spinning in the mount like everyone else's kit does. Iluvatar_Bzh gave us that great idea. 

These models will fit a Prusa, but you will definitely require new firmware. 

All models printed 0.2LH, 4 walls, 30% 3D Hex, petg, abs, asa, pc (I use asa)

What you need:
2x MGN12H Linear Rail Guides 345mm
3x MGN12H Linear Guide Block (3x long) 
OR 
3x MGN12H/C Linear Guide Block (2x long 1x short)

M3 T-Nuts 8x 8mm 
M3 Screws 8x 18mm
M3 Screws 4x 20mm
M4 2X T-Nuts 8mm
M4 Screws 2x 14mm

Increased nut slot size for rear left and right blocks. T-nuts were a bit too tight to work with. 

Added a minimal version of the rear mounts. Will make installing and tightening somewhat easier.

Special Thank you to Iluvatar_Bzh for his t-nut idea on the rear rail mounts.
