Let's make a part: Milling Steel on CNC Router (Gantry Side Walls - Reboot Series) 

Go for it! Start gently, do some testing and you may be fine. Good luck!

Depending on the control Software this is not too bad. With linuxcnc 2.8 this works quite well. I recommend one homing sensor per driven axis, so that offsets can be used to square XY

@@MinistryofBrokenEndMills thanks for the quick reply! I'm running 2.9 on Bullseye, so it should be just fine. I'll definitely add another endstop to the second Y ballscrew drive when I can allow for it, in order to correct for gantry racking. Cheers!

@@solverbox Maybe I am misunderstanding. You absolutely need a second stop, otherwise, you will have a bad time getting this to work as you lack a reference. Good luck!

@@MinistryofBrokenEndMills yup, gotcha on that one. The frame was built by another hobbyist, and I'm currently upgrading it with my own control and modifications. Independent homing of each driven axis is definitely on my list of requirements.

2.2kW; St-52/S355/1.0570

These are not steppers but Delta ASD-A2 Servos with 400W on all axis.

It's an MQL System based on a peristaltic pump. Sold by end cnc and is named ColdEND: www.end-cnc-shop.de/coldend-sets/

Hi, the original design this is based on has not been released. Accordingly I will not release it myself. However, I guess the photos help in designing your own. Linear trucks apart as far as feasible, spindle centreline as close to the linear trucks as possible (defines the slant angle) and as high as necessary within reason. Regarding a longer x axis: difficult to say as it depends on what want to do. I guess it would be alright. However, keep in mind that this particular machine noch only uses a 200x80 heavy beam but also has 10mm aluminium bolted and glued to it. At 1000mm the sag will be real. Length of the ball screw shouldn’t be an issue.

@@MinistryofBrokenEndMills thank you for the feedback. I would generally use it for wood, but would like to do the occasional steel milling just like you did with the side plates.

The same as for roughing the outside with adaptive. Hoffmann Holex Pro Steel 203044 8mm - in hindsight: 6mm would have been easier.

It’s a Jianken JGL80 Iso20 with 2.2 kW (see other videos). I have had no issues since I bought it in roughly 2019

@@MinistryofBrokenEndMills Still happy with it? I am looking into an ATC spindle these days and between you and Fox, Jianken may be the ticket. I also have 3 Delta B2s I need to put on a stepper driven machine. But had a tuning issue when I first tried and my circles turned oval. So, pulled them again and went back to the steppers until I can find more time to deal with this:)

@@AntiVaganza still happy, Till the day I sold it in favour of a bigger spindle. Jianken again and the new owner is happy too.

@@MinistryofBrokenEndMills That's good news, thanks:)

Jianken JGL80-2.2-iso 20 24k 230V an Hitachi wj200 mit 2.2kW single phase

Max is 24kRPM, min: depends on the vfd - down to 4500 rpm was ok; 6k is advisable

You can calc the rpm from vc and the tool diameter. Somewhere between 5800 and 8000 rpm.

@@MinistryofBrokenEndMills Sweet to see it still has enough oomph down there. Maybe more poles than the regular 24K spindles?

@@AntiVaganza No, 2 poles (1 pair). It’s quite a light cut and load was at >90%

@@MinistryofBrokenEndMills Thanks for elaborating:)

Apologies for the late reply: Yeah, I got that a lot. It worked fine though and thus I am not complaining. Made workholding easy and the cutting forces are minimal anyways:).
