I'm not sure why but it was always set to 2001..the .pro and screenshot show it. I restarted UCCNC multiple times with that settings.

Dan - you are right that the session dump were taken when the setting was set to multiple registers. But I tried the single register option before that and it did the same thing. In fact, I tried...

Thanks, robertspark. You are right about the SG+/SG- signal. I was able to get the communication going after replacing the usb adapter. I guess I'll be returning the faulty one. The serial port...

The manual can be found here https://www.automatedpt.com/wp-content/uploads/2012/06/VFD-M-User-Manual.pdf

Here is a page on the VFD from the manufacturer website...

Does anyone actually have modbusez working with a delta VFD-M inverter (3HP)? It seems to do nothing for me. I've set Pr. 0 to 3 (RS485), Pr.1 to 3 (rs485), pr 88 to 01 (bus address), pr 89 to 1 (COM...

I was waiting on some parts for the electronic portion of the build. The gantry supports were installed and adjusted for plumb/square.

I made the same mistake with my first CNC as well. Therefore, I'm doing everything I can to maximize the rigidity of this system. The speed and accuracy of a CNC machine greatly depends on its...

I installed the profile rails and initially use the top surface of the aluminum rail to roughly mount it. Afterward, I jig up the gantry riser to allow me to indicate off the epoxy surface to adjust...

I waited about 16 hours before taking apart the wooden mold and clean up the epoxy. There were quite a few small bubbles so I use a flat plate and sand paper to lightly sand down the bubbles. I also...

I had troubles getting the precision cast epoxy. They seem not to care too much about selling to a DIY guy like me and keep pushing back the pick up date. So I switched to using West System epoxy, 1...

I made a change to the plan regarding the leveling feet. I decided to use leveling casters to help with moving the whole machine into is final space. I had these casters for a long time. They are...

I use PL 8X to glue on the steel plates. The 8X is pretty thick and helps fill some small gaps. Notice the holes have been drilled into the plates on my drill press. I'll use these as guide to...

I cut slots for housing the nuts to bolt down the extrusion/steel frame. It is about 2" from the top, 2" wide, 1-1/4" deep, and 1/2" in height. The width of the slots (2") allows some degrees of...

There are a few things that could be wrong: your R&P drive connection to the gantry riser isn't solid enough. You need to go back and double check the collar on the 3/8 bolt that hold the drive to...

Thanks, Crhis for the diagram. That's exactly what I needed. I'd love to build the whole thing out of steel just like yours but I have neither the skill or the proper equipment to build and move it...

Over the weekend, I managed to paint the frame. I also cut the steel base to size and tested them for fit. The steel plate is 3" wide and will be glued into the wood frame with polyurethane glue. ...

Thak you and please post it, Chris. On your ClearPath STEP/DIR, did you use a 1K resistor between the +/- for long cable run (it's in the ClearPath manual)? I plan to use RJ45 and CAT7 cable for...

Gerry - what's the make and model of the relay you are using for the spindles?

It took a while but the LVL is complete and ready for painting. The frame design was modeled after a tried and true woodworker Nicholson bench. I'm very pleased with how it turned out so far. The...

I'm working on getting the aprons for assembly. A track saw is very convenience for cutting down long boards. The aprons are 14"x120". I've also picked up the steel bars. They should add about 200lb...

For Z axis, I want to get 0.25G accel and 400IPM rapid. The main reason is for it to be more efficient at 3D carving. The Z ball screw is 1610. I already had this Clearpath motor CPM-SDSK-3432S-RLN...

This is a close up of the stretcher to leg joint. The two domino secure the stretcher to the legs along with glue on the back side. The setup results in an extremely rigid connection which prevents...

The width of the extrusion is 40mm or about 1-9/16. The width of the apron is about 1-5/8. So if I build a channel for the epoxy, the side walls would be right in the area where the extrusion sit....

Another problem with pouring the epoxy directly on the wood is due to the width of the apron, the area wont be very flat due to meniscus effect.

I ordered the HGR25 rails and blocks from Motion Constrained website. Total come to about $1400 for 2 118" rail and 2 62" rails. The 25mm rails are pretty beefy.

The aluminum extrusion cost would...

I managed to joint the legs together today and put on the levelers. The leg levelers are just hockey pucks with 3/8" hardware. The screwed in plates were from eBay, about $2/ea.
...

I plan to use 3/8" thick x 3" wide A36 steel flat bar to connect between the LVL frame and the aluminum extrusion. The steel bar would be epoxied to the wood frame. Would some kind of fastener...

Previously, I cut some aluminum parts on the old cnc for the new one

Cutting 3/4 aluminum gantry riser plate

Gluing up the leg assembly. Each leg is 5.5" wide x 3.25" thick x 32" long. The stretchers connected to the legs via glue and 2 x 12mm dominos/ea. Each pair of legs have both top and bottom...

My previous CNC was a CNCPRP Pro v-con system. It was ok for small jobs but not rigid enough for serious 3D carving. I was also having problems with achieving accuracy +/- 0.005 for certain parts. I...
