The Ups & Downs - Installing the HDZ

I received my HDZ today around noon time. Just going through the installation instructions as it gets progressed.

The Shims. The instructions say " Shims - Please fit it with the bubble side up i.e. on the left and not in the right. If your V-wheels are not turning freely check this washer.". This comment should have been placed at the beginning of the V-wheels instructions instead of the ends. Even though I had it right, the comment made me re-check the washers.

Now, I’m completely stuck on the X & Z limit switches. Using the existing bracket for the X limit switch & attaching it to the 2 threaded holes on the right side as the instructions say, this put the switch higher than the end-plate where it’s supposed to make contact. I cannot flip the bracket and make the switch on the bottom instead of the top because of the V-Wheel.
For the Z limit switch, I have no clue where would the included bracket get attached to?

Also, I’m using the Carbide Compact Router tell I receive the 800Watt Spindle Kit that I just ordered. Attaching the existing spindle mount to the EZTram Mount, the 2 screws are not flushed in. The screws heads are sticking out a little, causing the EZTram Mount not to be flushed when mounted as instructed.

Sincerely appreciate your help lads.

for the Z limit switches, you need to put the metal plate just below the Z motor (I’attached a picture at Beaver products for both X and Z limit);
another thing, the screw that came with the Z limit switches you cannot reuse, there is a new screw for in the HDZ kit that is shorter.

One more thing that is very weird, I don’t have the “Use HDZ Option” in Carbide Motion Settings. All what I have is the machine list, where I picked XXL. Then the “Send Config. Data” button.

make sure you have at least version 4.17!


I just re-DL & installed new. Still the same. Software Version says 4.0.416 though.

I was able to get build 417 using your link. The latest version available from Carbide is build 416 which doesn’t support HDZ. I think this should of been addressed in the instructions, and specially to people who ordered the HDZ. Also, it states it’s a Development Build and to use at your own risk.

At it says:

The HDZ is supported by CM 4.0.17 onwards - do not try to use an older version.

The switches activate on different things than the stock ones do. Look at the pictures in the instructions closely and it will make more sense.

Given the HDZ is an official C3D product now, when will CM 4.17 become considered a stable release? The “development build” is dated July 2 and has limited changes from 4.16.




Anyone know how I can download CM 4.0.417?

Finishing with my HDZ install and can’t find the necessary software to be able to use it!

Yeah the link above appears to be broken. @WillAdams ?

CM417 is in beta:


The product seems to work fine, but I had to search and finally find (with this thread) the 417 release. I’m a bit disappointed that there wasn’t a note in the store product description and the box of where to find the appropriate (beta) software.

I’m still using CM 318 because I am lazy and have not upgraded to GRBL 1.1 and CM 4xx. I just use a 1.25" aluminum spacer on top of my HDZ and re-home if I need to use the bottom portion of travel.

Again, yes, I know I am lazy. . . :slight_smile:
