Here is another update.
I designed this PCB to add three relays and fix a problem with the cheap Chinese RNR motion control board I am using. The RNR board works fine but I had linearity problems...
In my build I used Gates timing pulleys and a Gates timing belt. The pulleys I am using are GT series with a 5mm pitch. The belt is GT3 type. I am not sure where you are located but in the USA stock...
This past weekend I made a bit more progress on the build. I machined 6 Corian parts to support the chip guard rollers. I was inspired by Wade O Design to use a similar chip guard roller setup. I...
Thanks. Here is a video of a Corian part I cut yesterday. This is an end support for a chip guard roller.

I am way behind on posting an update to my build.
Here is the table temporarily mounted with 8mm spacers holding it off the linear rail trucks.

Here is a small progress update:
I aligned the Y axis screw to better than 0.0005 inches with respect to the linear rails and tightened the bolts.
I also made a ballscrew mounting bracket. I...
The next step was drilling the holes for the Y axis screw. I made a smaller stone guide than I used before and started each of the four holes that I needed. I used the same drill and bit as before...
I have gotten bad about taking pictures as I work. The machine mostly looks completed at this point so I guess there is not too much to show. I installed the Y rails to about 15 inch pounds of torque...
Thank you for the encouragement.
Here is where I am at as of today:
I did the second round of epoxy to secure the inserts for the Y axis rails two days ago.
Yesterday I used a sharp chisel...
Thanks. The granite came from KBC tools. It cost about $370 including shipping. Grizzly is a good option too for about the same price but they were out of stock at the time I ordered.
Here is a...
Next was the hard part- drilling 38 holes in the granite plate. I used a 14mm sintered diamond drill I bought on eBay. After 38 holes it still has plenty of life left. I made a hole in a piece of...
I had some time off for the holidays so I made a decent amount of progress on this machine. The columns were put in the lathe chuck and the end plates were skimmed flat and square to the 5x5 inch...
I completed the mounting of the X axis ballscrew.

The welded support columns came in as well and I am getting ready to...
Here is where I am at on the Z ballscrew assembly. I finished the machining on the mounts. I also cut the ballscrew to length which was not easy. I tried to part it off on the lathe but it was far...
Here is what the gantry looks like with the spindle test fit.

I had a small company machine the ballscrew mounts for me...
Next I indicated the second X rail using the master rail as a guide. I got these parallel to about 0.0002 inches I estimate.

I am putting this in the wood router forum even though I plan on cutting metal and wood with this machine. Here is my progress so far.
I started with a 24x36x4 granite surface plate. It came from...
Here is an image of what I plan on building. The base (24x36x4) and gantry (18x24x3) are both granite surface plates. I will have a U shape cut out of the gantry surface plate by waterjet. Thank you...
Thanks for your comments. I primarily want to be able to machine plastic, wood, and aluminum and hold around a 1 thou tolerance. I think you may be on to something with the idea that there should be...
In my design the gantry is fixed and does not move. I have attached a simple drawing to illustrate the area I am concerned about. I am worried about the difference in expansion between the table and...
Hello,
I intend to build a gantry mill/router using a granite surface plate as the base. To this base I will bolt two hsr25 rails 10" apart. To the carriages that ride on the rails I plan on using...
This quote has been filled. Thanks to all those who responded.
It appears that the scale of the STP file was wrong. Attached please find a DXF.
Hello,
I am looking for a quote for two copies of the attached file for a total of 6 pieces. Please note that all holes are 6-32 except for the two with a note which are 4-40. I am located in the...
