With respect to the current Raptor machines is anyone aware of a supplier of a prebuilt and wired control box. Cncrouter parts do seem to offer something has any one used this on Xzero mechanics?
Thanks.

so, anyone in the toronto area want some xzero parts?

after a long and circular path around what to do with my predator and my too heavy ATC spindle, i bought 2 brother vmc's....

yup. haha.

so, now, i know exactly what i need from the predator - a pure woodworking production machine.

so, im keeping the spindle, and some of the predator frame, z axis, ball screws, rails, etc.to build into a much heavier steel frame, and ditching the bits i dont need.

heres what i dont need:
predator 40 wide end frames.
predator uprights.
4 nema34 motor mounts.
z and y ball screw nut mounts.
4 ball screw bearing blocks (no bearings)
2 x ball screw nut mounts.
modified y and z saddles with clearance for oiler lines.

theres some scuffs and scratches on some parts from assembly and sitting around, but otherwise, they are basically new.

also, i have a set of 4 leadshine easy servo nema 34 kits - the one that made the machine run at 1000+ipm in the videos shown earlier.

you can talk to george on getting the remaining parts to build it up, or go turn it into a DIY adventure. fun for the whole family!

What is the model # of your easy servos, and are they the 110v or the 220v ones?

110v. ill look up the model later.

[Andrew22]

110v. ill look up the model later.

Are you using 25mm pitch screws with those? Right now I'm maxing out around 600 ipm with a 10mm pitch screw and 220v easy servos. According to calculations I should be able to double that, but the drivers throw out a position fault error if I push the speeds any higher than that.

well, depends on how we go about tuning and your moving masses. with my 50+lbs spindle, i settled on 1000rpm and 0.5G acceleration. so 984ipm on the 25mm pitch, and 393ipm on the 10mm pitch z axis. i had the following error fault set to 60 counts using the default tuning, which is pretty tight at that speed, since generally that's just rapiding. at lower " cutting" speeds the error was reading on the display only 4-5 counts. at full speed, usually no more than 30-40 counts. in essence, i was running them as stepper,s with stall detection. i was not utilising the tuning yet to keep things tighter.

it should be noted a stepper is always up to a full step behind the target. thats 20 counts in this case under heavy load.

According to calculations I should be able to double that, but the drivers throw out a position fault error if I push the speeds any higher than that.

i dont see how you could double that. these motors are rated for 2000rpm, and have little torque at that end. thats 787ipm. so id say 600ipm is good - and probably higher than your safety margin should allow unless the load is very small and acceleration very very low.

i was able to hit 7-800ipm with mine with no load on the Z, with the position error set to like 10000 (basically, off).

787ipm

[Andrew22]

The 220v ones are rated for 3000 rpm (part of the reason I bought them) and there should be still be enough torque to get over 1000 ipm for rapids. You're right about the tuning though, I probably would get better performance by going into the drivers and tweaking the settings to allow more torque. There's lots of little details I still need to work out.

so, it seems george will be away for a bit. send him a big get well soon!

while he is away, hopefully people with xzero machines and expert knowledge will be able to help out the new buyers with their tech issues.

Question for someone in the know. Where can one buy the material that George uses one his Al table tops. It looks to be the standard 1/4" slots. All I can find are the metric versions of the extrusions on the web.
