A little bit of a walk around my machine and watching it now happily machining brass...

a lot of modifications to get to this point, but must say the result is worth it in the end.

Just been pulling together a list of all of the updates to my Genmitsu 3018-pro: Upgrades to a 3018-PRO - glue-it.com



1. Spindle - angular contact bearings, belt drive and ER11 chuck that I have ground to a higher accuracy
2. Z-axis - Tiamu aluminium frame and homemade spindle holder
3. X-axis Rails - changed 10mm round rails to MGN12 linear rails
4. Y-axis Beams - changed 10mm diameter to 12mm diameter and upgraded linear bearings (the balls in the bearings are now spherical!)
5. Sand Bag Damping - simple and cheap way to add damping to any machine (also used in my large manual mill)
6. Frame Stiffness - added brackets that triangulate the uprights
7. X and Y Axis Stepper Upgrade - point of caution is that the controller has a limited current output and hence this might be the limiting factor
8. Controller Upgrade - Finally I checked online and realised I was running an old original version of the controller. Upgrading to the GEN3 controller has made a significant improvement and no more jumping / missing steps on the X-axis.

This Sainsmart Genmitsu 3018-pro or otherwise now known as Trigger's Broom works really well machining brass and aluminium, tasks it just could not achieve out of the box.
