Taz Pro 12mm Smooth Rod Y-Axis Upgrade - See WARNING!

thingiverse

WARNING! YOU WILL NEED TO MODIFY THE MARLIN FIRMWARE AND CREATE YOUR OWN VERSION TO USE THIS ON A TAZ PRO OR WORKHORSE EDITION AT YOUR OWN RISK!!! Failure to do so may cause damage to your printer. Use with caution!!! Because the Taz Pro (and possibly the Workhorse edition) use Z-Max as part of their homing sequence, and because there is no Z-Min switch, the Taz Pro relies entirely on a pre-calculated print bed volume for initialization. If you change the amount of Z space available for a print and don't update the firmware accordingly, you're likely to face significant issues. The constant that needs changing in Marlin is located in Configuration.h - Search for define Z_MAX_POS xxx and adjust that value appropriately before flashing the new firmware to your printer. Print with ABS. The parts are designed for ABS print tolerances; if you print them with PLA, expect a lot of slop in the part. To ensure optimal prints without blobs all over the inside, set the following Cura Print options: - Layer Height: 0.27 - Combing Mode: All - Retraction Min Travel: 5mm - Print Speed: 30mm/s - Cooling: 5% (assuming you're using a Titan Aero design) - Temp: 255c (depending on your ABS) - Optimize Wall Print Order: Yes - Infill Percentage: 60 - Infill Pattern: Octet/Tetrahedral - Wall Line Count: 3 For the smooth rods, the 12mm smooth rods from a Taz 6 will suffice - however, please note that the length has to be correct to fit in a Taz Pro as the Y-Ends physically cap the rod ends. You'll need to either whip out a steel chop saw and sander to clean the end result or order the exact correct length (whatever the original 10mm rails were). This modification voids your warranty, and improper execution may damage the machine. Use at your own risk!
