## Questions & Answers

**Q: Ok so when my z axis plunges into the material there is play and the mill tip gets deflected up will this solve that?**
A: The anti-backlash spring is a lot stronger that the original holder

**Q: I have the 3018 pro but the stock spindle diameter is 43mm. I cant find an upgrade for a 43mm diameter z axis mount. Or am i missing something here?**
A: Hi,
Firstly the image shown is for the '3018-PROVer/PROVer Mach3/MX3', not the 3018 Pro! The 3018 Pro version is available on the same Amazon page as the 3018-PROVer/PROVer Mach3/MX3, to the immediate left of the rectangular box stating '3018-PROVer/PROVer Mach3/MX3', just left click on the to the left of the rectangular box & the page will update to the '3018 Pro version of this upgrade  (same price).

That said, you will need to buy a 300W to 500W spindle motor with 52mm body diameter to use this upgrade & discard your existing 42mm motor.
You will also require a new separate power supply to suit the new spindle motor along with a PWM speed controller to drive the new motor.
I have done the above upgrade for my 3018 Pro with 300W spindle motor upgrade, & now get really good cuts & finishes from my 3018 Pro.
This does involve additional expense but is well worth the investment.
Regards
Laurence Barron

**Q: What is the linear bearing diameter? I am looking to get this upgrade and I have 10mm stainless steel rods.**
A: Hi, I ordered the Genmitsu Aluminium Z Axis Spindle Mount 300-500W Spindle Holder 52mm Diameter for the 3018-Pro, & its' linear bearing diameter is 10mm. In the same Amazon page as the the Prover version, lower down the description you will see selection boxes for either the 3018-Prover & the 3018- Pro versions, so depending on what CNC machine you have, simply select the appropriate box. I do not know what the linear bearing diameters are for the the Prover version, but the 3018 version are 10mm. I hope this helps.

**Q: Will it fit a mostics cnc 3018 pro**
A: It only fits after the bottom X guide was removed , then moved down in the Z direction by 1mm.
Note that the 2 parallel X bars is to hold the Z axis module. (The gap is not wide enough).
I originally forced it in.(BIG MISTAKE).
I had to re-drill the side support holes for the bottom X axis  shaft after filling the original screw hole with glue.
The glue hardened and dried, then I drilled.
The 1mm increase made the Z axis module travel easily.
Measure the gap (exact centre to exact centre before installing).
