I bought about 20 of these motors for some prototyping we are doing at work for a robot. With both the hbs86h and hbs860h drivers. There are a few more options on the hbs860h for a bit more fine tuning, but usually not needed. People should be aware that the coils are sometimes wrongly labelled on the motor vs the driver, so if you start it with an arduino or another mcu with a simple code in c++ or python and it is rattling or shaking or not moving at all. Try to switch one of the + and - on one of the coils (A+,A-,B+,B-). Just annoying using time debugging for people buying their first one.
very nice if u have the money and time...another option that is very economical and less invloved would be to just fabricate 1 or 2 additional supports on the frame for the bed to mount to to eliminate a lot of the flex.....the alum extrudion is not the main issue ..the issue is no support underneath.
What machine is this ? Did you upgrade it at all or is it stock? I’m looking for a cnc under 800 dollars that can cut aluminum well enough for usable parts for knife handles that need somewhat tight tolerances
CNC 6040. Is the Y range really 600 mm (23.622 inches) ? One RU-vidr (Csongor Varga) said the Y travel is only 50 cm? Can anyone tell me the exact distance of the longest axis? "X,Y,Z Working Area 600(Y)*390（X）*120(Z)mm"

3:56 Is there a coolant feed to the system? Didn't see the purpose of it in your vid. I'd be using it to cut aluminum mostly. They have a model on Amazon that mention and shows (in the pics) a spindle for a 4th axis. Oddly, they show another on Amazon at the same price, but none of the pics show the bed-mounted spindle for the 4th axis. Did yours come with that?
Hi Thanks a lot for the nice series of video. Thank to you, i bought the same setup and start aluminium few days ago. But i have a strange issue, i have a kind of step effect that is more and more the deeper it mills. I choose a really small layer deep (0.2mm) to avoid too much effort and go slowly into the material but it has no effect. I did the same part into mdf but i have not this issue. It is like the steper mottor loose precision with the time or with a more harder material. Do you have an idea may be ? Again thanks a lot for your job !
I cannot send the picture to the machine? I dont have the the "arrow down or up button" to send it to the machine. When i hold the center button on the machine it starts to make something else. Is there a newer software? What am i doing wrong?
I appreciate you making this video 👍 But I don't get why you put a glass plate on the bed and shim it, because you need to calibrate your spindle to the bed on which your work pieces are held down. I also note that your bed is too large, the cutter can not reach all corners to flatten the entire bed, leaving you with cupped bed which is not really handy?
I've had the same issue. But, I solved great deal of it by keeping a constant flow of compressed air directed at the cutter. Get those chips out of there as they get ground between the cutter and the previously cut surface. The second thing I did was leave a fairly large finishing allowance; I leave about .010" and then make a final 2-3 passes to clean it up. Finally, I switched to .125" cutters. I'd prefer to use .250" but they are too big for my work. I think the .125" flex too much so I get them as far up into the collet as is practical.
I have noticed substantial noise changed at 14:00 when the is moving from 6 o'clock to 4. This is probably flexing of the Z axis assembly it get stretched while the moving on Y axis . It could be back plate flexing or bolts stretching
I wish you would have gave the specs of your machine. It looked pretty beefy and I would have thought it would have easily handled the job so I am a bit disenfranchised looking at the purchase I made… I am looking to do similar work flows.
After 4 year's of use do you have any rust on the steel bed. I got ½" iron plate that i got from a an ironwork friend and i am planning on doing the same thing. The only what worries me is the water mist cooling system i have. I probably would have to paint the iron first
Huh, I don't think I'd thread a hole in the gear, install a socket on the end and chuck it up in a lathe just to get the bottom portion out-wow! Can't you just use a larger piece of material, get it close to the bottom and use a punch to tap it out?
Hi! ingenious this closed loop project. that's exactly what i've been looking for. unfortunately i can't find your code anymore. have you already deleted it ? greetings, Michael
If you run a couple of pieces of angle iron along the bottom of that plate inboard a bit from the edges, and just bolt it up from the bottom, it will get rid of any of the rest of the slop in the machine.
Really nice, i took inspiration from you and did the same upgrade than you concernant the metal plate. It is so heavy ! Just a question what kind of drill do you use please, because my plate is so hard to drill that i just use two screw for the moment . Thanks again for all the support you bring to me
