I don’t know anything about holes mis-aligning. That might refer to a user error, but we have never had any kind of hole QC problem that I can recall on the HDZ.
The mount is a beast. I originally had a spindle manufacture adapt one of theirs, however the quality was hit and miss and we had to junk allot of them. In the end I made the decision to go to a full machined mount - yep we machine down a giant chunk of aluminium! It’s one of the highest quality mounts out there.
Stock wise, @robgrz made my morning and setup the HD category in the store last night.
I don’t have a tremendous amount of time with it, but I have no complaints so far. It is very quiet (certainly as compared to the router - quiet enough that the cut noise overwhelms it), is relatively light and, as noted, will fit in the stock mount. That fit what I was looking for as I didn’t want to deal with separate cooling - we’ll see whether I come to regret that choice or not.
I will echo @The_real_janderson comments on the real need for a spindle and or HDZ for cutting plastics, aluminum, brass or copper. The cheap route besides using a single flute would be to purchase a Makita router that would give you 10 to 30K speed range. I also have an EasyTram and it makes it simple to tram along the X axis but you have to use shims to trim along the Y axis but it is fairly simple job. The plans were/are available at BeaverCNC.
Now I wish @Luke would look at a proper solution for adjusting all axis tramming for a future release of the Shapeoko and/or a retrofit.

Thank you. I discovered that the original Spec NEMA are not powerful enough to drive the CNC pro. I thought about going with the HDZero spec, But didn’t want to have to contend with the 220 power supply.
@The_real_janderson - what specific end mill do you use for acrylic & polycarbonate? I cut the same materials at 38IPM at the lowest speed on the DWP611. I’ve tried higher speeds & feeds without much luck & would love to get up near where you’re at.
Just watched the installation video on YouTube from Mr. Beaver for the HDZ. Very informative and I think I’m ready to purchase one.
For those who haven’t seen it the link is here:
Question - the forums and carbide 3d site state there are 270mm height required to fit the HDZ in an enclosure. In the video it is mentioned that the HDZ is in ver 3.3, and I’m noticing the spacers located on top that hold the z axis motor are no longer there. Is the height requirement still 270mm or has this decreased with the removal of these spacers?
Thanks
Thanks Luke for confirming that. I think that’s enough info- don’t need the pictures or measurements unless you feel like providing them.
More important for me- are the HDZs in stock on the c3d site the 3.3 model? The older configuration wouldn’t work in my enclosure, ironically I have exactly 270mm of clearance which doesn’t give me any wiggle room, or room for the dust collection hose.
My parameters are around these:
Depth of cut ~= 1.5mm
Chipload ~= 0.15mm/tooth
Radial depth of cut ~= 30% of endmill diameter
So just as a reference, for these endmills, at 20,000 RPM, I was running about 118 in/min. Much faster than your 38 in/min. You need to go a lot faster in plastic in order to keep chips large and prevent melting.
Just noticed that Leadshine’s DMC860H delivers seem to what AC vise DC.
I say seems, because on the spec sheet it says “ Supply voltage up to 80VAC or 80VDC Output current up to 7.2A.” I guessing the drive has probably has a rectifier bridge as the first thing in the power circuit, so AC or DC does not matter. Any thoughts?
One thing to check is if thats half power or full, at 7.2a that sounds like they will be more suited to nema 34 rather than 23. Make sure you run them closer to half output, 7.2a will be OTT on normal wiring etc.
I really like your enclosure. I am curious if it adds structural rigidity to the Shapeoko XL? Do you have a similar enclosure for the XXL? If you don’t, I still would be very interested in seeing some additional photo’s and measurements as I could extrapolate for the XXL.
