RPM >=?rpm
Power >=?Watts (I see 2.2kW as a common rating, but how much do we actually NEED, at the tool?)



You can use feed and speed calculator.

FreeCad is cad program, not cam. You can try this: https://www.autodesk.com/products/fusion-360/free-trial

Mount the motor first and if it still sliding down, then use brake or springs.

Use FSWizard app. It is free for android and iPhone.

Are you sure, that power supply is working correctly? I had similar problem and found "cold" solder in power supply output connector.

Hi.
If You need it for business, buy machine with better local support.

If you are happy with the other axes speed, just use two ballscrews and motors for the gantry.

Hi.
You have 1200mm gantry and one ballscrew. What speed do you expect from this design?

This card is for torch height control, to fire the torch you have to use output from motion control board. Do not use solid state relay, this is not suitable for plasma....

Question: 80kg for X axis SRB 20 support rails is too heavy or not?

sbr 20 dynamic load rating is 860N. It means, that one bearing can be loaded with 86 kg.SBR20 LUU dynamic rating is 1764N...

Wall thickness 6mm is minimum. I have used 250x100x6 steel tubes for my router.

Leadshine Easy Servo Driver HBS86H and Hybrid servo motor 86HBM80-01-1000 from Aliexpress. Gantry is1200 mm.

Hi.
You can use simple power transformer for stepper driver(20-70v AC). Connecting two swiching power supply to get 96v is not good idea, and you do not need dc voltage. I got transformer from old...

From the first post I see that you are from Canada. MyCNC board from "http://www.bevelcutting.com" would be my first choice.

Maybe epoxy. 302196

What is the length of the ball screws? I think that the ball screw inertia is too high for the NEMA 23

Hi.
For my last build I bought Hiwin linear rails and ballscrews from Mekanex. This is a Swedish company, and they have pretty good prices.

Seems that spindle plate is 20mm too short, now I have to make new one. I do not like that Herz 2.2 kw air cooled spindle. It is too noisy and at low rpm...

Hi.
You can get linear components from Mekanex - transmission equipment - linear movements . 4.1 mH motors will be better choice.

Here are some pictures of the machine that I build. Maybe you can get ideas from here.

What program do you use to generate the g-code? I had a similar problem when I used the BobCad-cam.
