I can't believe it has been nearly 6 years since I started the thread. An I was truely surpirsed when I read that the module was now included in Linucnc. Thanks to those who continued to improve and...

The debate between windows and linux will never end becasue the two operating systems were developed for different end users / markets.

Go with the PFC. It will serve the purpose fine. Building a welded steel frame or bolted connection? Just remember that ANY steel section will bend when subjected to localised heating due to welding....

Taras,

Great to hear that you figured it out. Great that they left the component of the circuit board.

I'll need to check my vfd settings. Not sure why your output is not as it should.
...

Taras,

Don't get discouraged. I too had a lot of problems trying to get the comms up and going, and seems that a lot of people are as well. A few steps that may help:

1. Do not rely on the...

Taras,

In custom.hal you probably have

# Load the Huanyang VFD user component
loadusr -Wn spindle-vfd hy_vfd -n spindle-vfd

which is my setup which uses the hard coded default settings,...

Taras,

Please check your config files:

Design is getting closer to being finished. Day to day life and work just seem to get in the way.

This pic is not a rendering... this is the new modeling environment in Inventor, oh so nice but...

A couple of orthographics... Does anyone have a CAD model of a 2.2kW water cooled spindle? and a spindle mount?? Would be much appreciated.

Thanks Scott

X-Axis carriage nearly complete...

Nearly there... Z axis to complete and then some cable management.

I've been tossing around a few ideas for tensioning the R&P drive. Turn buckles take up a lot of space so this is my take on using a compression spring. A little more time consuming to make but...

Finally got a little more work done on the rack and pinion drives. I purchased all the pulleys and bearings ages ago from Stock Drive Products before CNC Router Parts brought out the R&P unit so I am...

No, drawings still in progress. I did a quick mirror over to show what it will eventually look like. Support frame still needs bracing but I'm thinking some cupboards in the base would be handy.
...

A couple more pics. I am planning to mount the ball screw through the centre of the 8020 extrusion to get the spindle overhang to a minimum.

Over the last year I have been collecting parts for a CNC Router. Initially I was going to build a Joes 4x4 Hybrid but then things started to evolve. I have enough room in my workshop for a 4x8 and...

Hi Bob,

I also have the G540 and a gantry style setup (although not built yet). With EMC you can do this in two ways. The first is to use Gantrykins to slave the two axes. This needs to be loaded...

Great news! That laplink cable would have a few pins swapped end to end...

I have a G540 running under EMC2. It was quite straight forward once I found a stepconfig file (try searching the zone, I'm sure I found it here). When I get a chance I'll post my congif files for...

I was referring to the VFD processor. It seems to get busy and ignore the Modbus commands. I have modified my c code to resend the command if a comms error occurs.

I did play around with the mult...

I'm curious to know how people are implementing an E-Stop with the drive, dropping the supply is the easiest, but not the most elegant. The external inputs don't seem to be active when under Modbus...

Huanyang VFD's have become popular with the router guys as they are coming out of China cheep with spindles. However, even though they have a RS485 comms capability, the comms protocol is not Modbus...

Plese, these are beta files and any testing feedback will be much appreciated. You will need dev packages installed to compile. Lots of documentation still to do.

Ok guys here it is. The following two archives contain the HAL component and the EMC2 config files.

Still trying to figure out why I'm getting comms errors but I'm starting to think that while the...

yngndrw,

I also grabbed one othe those as well (currently using it at the moment) as I thought I had some problems with the USB adaptor. Debuging the software was a lot easier by making a RS485...

Henrik,

Thanks for that. I'll try adding to the includes. I think that the comms error is in my interpretation of the return message from the vfd. Now that I am sending and receiving a lot of data...

yngndrw,

I know some ozzie guys are currently testing a Mach plug in which they hope to release soon, not sure if they are going to release the code as open source.

All of the "Drive Configuration" infomation is read off the VFD and is used to set the minimum and maximum rpm etc.

A bit more work on the hy_vfd component and pyvcp today. Nearly got everything working the way I want. Scan rate is 2 seconds at the moment which is fine fow most things but now that I have the...
