CANDCNC on Torchmate Table

Post by Stanmyers00 » Mon Oct 04, 2021 1:26 pm

Has anyone run the CANDCNC G5 system with stepper motors on an older Torchmate table? I have the table with the turnscrew drive on the gantry and rails. I am wondering what kind of feedrate\cut speed I can go up to. The original Torchmate set up was maxed at 175 IPM. Thanks.

This was a torchmate upgrade

CandCNC G5 bundle

I upgraded my 10 year year OLD table to the G-5 bundle with the RS-485 kit.
I would highly recommend this CandCNC upgrade for two reasons, first of all the, plug and play system, and outstanding Tech support.

I was so ingrained in having to do all settings by hand, Tech support was a great help in getting me started.

Thanks CandCNC.

I have heard nothing but good things about the C&CNC Torchmate retrofit kit. Flashcut also has a Torchmate specific retrofit kit but I believe it is a little more costly, both are longstanding reliable brands.

I have Cand system, Works well. I saw my cousins Torchmate and decided almost anything could beat it on gantry power and speeds etc. I am working on switching to linux QTplasmac with clearpath servos as I have time, just another option if you like to fiddle.

Thanks everyone, I do have the system installed and running. I am trying to figure out what cut speeds I can run with the new system. I regularly cut thinner metals, so with the old Torchmate system I had to manipulate the amperage to get good cut quality because of slow cut speeds.

What you wil find is the higher torque motors you got with the upgrade system will allow you to get better speeds before you experience the dreaded lost steps . The beeter toolpath tracing and dynamic trejectory control will let you cut at faster speeds and while Real time Anitdive on corners an d turns will stop torch dives . You should be able to approach the required cutting speeds on the chart and use the integrated cut charts if you have a Hypertherm of any type. You can raise the Preset voltages if you want to cut a slower speeds to maintain the proper cut gap height).

Note to cutoweld: We have a new G5 XL servo system that uses the Clearpath servos and our CommandCNC version of LINXUCNC . You can choose between the 34 servos or the 23 and mix and match them. Servos are not cheap but they offer some advantages if geared correctly for a rack and pinion table. The G5 Xl controller has all of the power features to run the Clearpath with centralized overload shutdown and servo fault shutdown if any axis faults . Panel indicators show which servo casue the shutdown.

Thanks everyone.

I posted this on the CANDCNC forum and was told 600 RPM's was an ideal working range for these stepper motors. According to my calculations I should get 200 IPM, a 25 IPM increase over what I had. Thanks again.

What did your steps per inch end up being ? The best way to find the operational point is to keep raising the Max Velocity unitl its starts to lose steps on detailed cuts then back a off by 20%. Also lower the acceleration some and you will find you can hit higher IPM . You can get by with lower acceleration due to the tracking giving preference to accuracy over constant speed . Down side is corner slowdown but VAD takes care of torch diving .
200 IPM is marginal for thin material . I have reports taht the original tables would start to have poor perfomenace about about 120 to 150 which really caused issues. You can't get step up gearheads I am aware of so chanign the raio with pulleys and offset motor mount is th eonly way I can think of to get more speed. ^20 steppers will do 1000 (actually as high as 1200 ) RPM with no load but tha tis not USABLE RPM in most cases. We have found that on a leadscew Z with ballscews and low friction guides that we can get up 900 RPM or more .

And there you have, solid info above direct from Tom Caudle at C&CNC, how can you go wrong with attention like that!
