News on the reveal of the new Sainsmart Genmitsu 3020-pro Max on 27th September 2021.
Enhanced design and increased Z Height of 72mm with the Genmitsu 3020-PRO MAX. The all metal spindle holder and 300W spindle makes metal carving easier.
Not limited to wood or extremely slow jobs engraving metals. The new 3020-PRO MAX can engrave brass, copper, aluminum and handles woods and plastics better than ever before.
Apparently, this already has lots of upgrades available:
Easy to Upgrade: Although our standard spindle can already meet the requirements of most projects, the control board and spindle holder still support the upgrade to 600W spindle, making the 3020-PRO MAX more powerful. Also, more and more upgrade accessories will come soon!
Genmitsu 3020-pro Max
Looking at the image and video, my first thoughts are:
- X-axis now has rails fixed to the aluminium extrusions – significant improvement on 3018-pro.
- All metal spindle holder – this should increase the stiffness, but we need to wait and see if they have sorted out the issue of wrong sized Z-axis rails.
- The Y-axis round rails appear to be the same as the 3018-pro. This is not a deal breaker, but let’s hope they have at least increased them to 12mm diameter.
- Increased Z-height – this will help, but not convinced this is enough for those who want to engrave pots, boxes etc.
- 300W spindle – again this is interesting, but it still appears that they have the ER11 chuck pushed onto the motor spindle. This means there is still an issue of runout of the motor, runout of the chuck and significant mass overhanging the motor bearings. It appears they have done nothing here to fundamentally sort out the issues with the 3018-pro.
Conclusions
An interesting upgrade with the X-axis rails that will hopefully significantly increase the Z-axis stiffness. We need to wait until 27th September 2021 to see if any of the other upgrades are worthwhile. The other question we have is how much is the Genmitsu 3020-Pro Max going to be?
First Venture into CNC
I bought and assembled a Genmitsu 3018-pro. Since then it has been a steep learning and upgrade curve to get to the point where I can engrave aluminium.
Tiamu Z-axis for Genmitsu 3018
Just bought a Tiamu Z-axis for Genmitsu 3018, my original plan was to machine this complete assembly from scratch. Then reason kicked in and I thought that as I could buy this for around £100 it was not worth me spending probably 3 days designing and making parts. Plus it was delivered really fast.
