Here's is the text directly from the Bulkman3D website: "Upgradeable Motors Achieve Commercial Speeds Our ULTIMATE Bee CNC has options to have its motors upgraded to achieve high-speed operation similar to industrial machines. Very few machines can match the rapids speeds of up to 30,000mm/min like the ULTIMATE Bee can with servos. This means much faster workflow and more jobs done. Competitor machines offer a maximum of 5000-6000mm/min."
I emailed their support, sharing my disappointment and this was part of the response I received:
"I it is not recommended to run the machine faster than 15000mm/min to preserve the life of the ball nut."
So I guess, even though they advertise it as a 500mm/sec machine, they only recommend running it at half that speed.

probably not worth it now, but a nice way of solving that can be to have the ballscrew static, and rotate the ball-nut. Can get up to much higher speeds.

might be also worth checking the straightness of the ballscrew? like detaching the nut, attaching a indicator on the head and see if the low point in the gooves is consistent over the whole lenght? the fixed ballscrew on my router has some resonance too sometimes. probably better but does not solve the problem completely.

Run the head all the way to the motor side and re-tension the nut on the end. This tends to happen with this kit over time. Just keep an eye on it. Otherwise, wow! What a great machine!

Great to see you are using servos. I don't like steppers at all.
|
THIS - when people say āball screws would have been better on that 3d printerā š
|
Yours sounds sooooo smooth compared to mine. I have a 1510. Iām curious if you did any little tricks when setting the thing up?
|
Maybe mounting the z axis motor upside down at the back so it's at a lower placer and use a timing belt and/or replace the back plate so the slider blocks could be mounted at more distance could help.

It requires the Ruida fiber laser controller? I was hoping that the laser source is compatible with the Ruida Co2 laser controller that I have spare.
What type of signals does the laser source require? Pwm / enable or more?
Does the ruida controller require servomotors or it also work w/ stepper motors?

Iām about to pull the trigger on this cnc but Iām opting for the (bottom of the range) High torque nema 23. Meaning that I shouldnāt have this problem right? I simply wont be able to move this fast.

Hi, I wish I would have seen this video before I pressed the pay now button. At the end, did you find any solution for this to be prevented?
|
The Bee uses 12mm ball screws. Most desktops use 16mm.
|
Instead using of ball screw you. Can go with rack and pinion with servo planetary box , it is more cost effective and you can achieve more acceleration
|
Nice progress. What are the servo motors?
|
Maybe oldham coupling could help
|
Is that also a masso Controller?
|
Watched your videos, but to late to warn you about ballscrews!
|
Wow this is so cool!! I really wish I could put a laser on my crossfire pro
|
You got the servos right?
|
What do you plan on doing with it?

You can help that with a travelling support that halves the length. Mount it on an additional carriage. If the screw od consistency will allow.
