Thank you Al_The_Man!
right. that was pretty much I have said. I tried at the beginning 2 stepper motors, but at the higher speed they are loosing torque and so I started thinking of AC motors.
My question is: is it...
does not answer my question, but thank you.
:)
Hi dazp1976,
steppers run on DC, so I don't think such a thing as "stepper phase" exists.
I used nema 23 motors (I actually tried other sizes, increasing them and the largest I used lastly was...
Hi machinehop5,
I need to motors running with speed about 2000 RPM (maybe higher in the future - I don't know yet. Have to try it first) and I need motors to keep torque value.
I used steppers...
Hi All_The_Man!
Thank you for replying.
Can you share, please, how to implement it? I need both motors be connected to one VFD, but have one the motors running in reverse - like you said - Railway...
Hi Algirdas,
Thank you for replying. What is the difference between spindle and motor?
I am thinking to equalize the axial load. Almost eliminate it by using cross-roller bearings at front of...
Hello Everyone,
I am building a CNC machine. It is not usual/well known machine and I need in it 2 spindles running with exactly the same speed and other parameters but in opposite direction to each...
yep! Thank you!
but again - how do you tune axis on linuxcnc? Am I missing something? Do you have any special tool for it? technique? Or, perhaps I did not see something in linuxcnc and my complaint...
:) )
BTW, I think, I could be fixed at the very beginning when I was tested each axis. However, I found it kinda difficult, because the way it is implemented in linuxcnc.
you can choose for testing...
Do you think, DJ, it would be better than adjusting ballscrew pitch number?
I am planning to check it again tomorrow and cut yet another part from the same file, to see how stable this change. I...
Hello Everyone!
just finished cutting yet another piece and it came out much better.
So, I was cutting a square with side 10mm. out of machine it came out 10.1 x 10.07.
it is not perfect, but main...
Thank you DJ - that sounds promising and probably is exactly what I need. Lemme try it.
I am using program I have written myself to generate G-code. It is pretty specific because of my specific needs.
My machine is not usual one - it cuts out element of any shape out of hard/brittle...
no, I haven't. to make it all run in opposite direction I will need to change everything - model file I have with all its lines in it, so, the program I have, which reads this model and generates...
you're right - I did not mention it. the reason being is because there is nothing unusual here -table is horizontal. My theory only is that - this machine has been built in my garage. and of course...
Hello CNCZoners!
I have build CNC machine to elements of mosaic. I am tuning it now, however I bump into problem I am unable to solve so far.
pieces I am cutting on it on Y axis are consistently...
Hello Everyone!
I need custom shaft for CNC machine I am building.
Can anyone, please, help to manufacture it for me?
I've been searching for shop to manufacture it for a while without luck so...
Hello Everyone!
I am building CNC machine and need custom shaft to be made. I don't have lathe and have only small milling machine. I've been trying to manufacture shaft on it, but not happy with...
Hi Jim and All.
latest news - after several days of communication efforts, I was able to obtain from Sainsmart wiring diagram for 1 Axis Programmable Controller.
I am posting it here, as I suspect,...
also, Jim, as I understand it: from motor driver pul (-) and dir (-) go to gnd on the motion controller - is that sound correct?
Thank you so much, Jim!
so... do I need to add three resistors? (according to this diagram).
and, yes, controller does include mini CD... and it contains one file - manual of controller in...
Hey Jim,
I got this chinese 1 axis motion controller, DQ860MA driver (wantaimotor) and nema 34 motor ( wantaimotor, 85BYGH450D-008). the manual for 1 axis controller is in chinglish. there is no...
awesome!
exactly what I need.
Thank you, Jim!
thank you, Jim!
looking at this, my understanding this controller won't be able to change the direction, so, I will need to add into circuit a polarity switch. Am I wrong or not?
thank you.
Hello Everyone,
I need make drive going to one direction up to certain point. as soon it reaches that point I need it go in opposite direction with the same speed it had before.
so, basically, as I...
thank you Jim.
though your suggestion look very nice, but unfortunately their software runs on windows only :( - I am using linuxcnc.
huge thank you anyway!
speaking of...
Hi Jim,
Thank you for quick reply :)
1. not very fast. actually rather pretty slow.
2.I am planning to use ballscrew drive
3. motion is linear
4.mass? it is in design stage, but I anticipate...
Hello Everyone,
I am looking here for suggestions on how to make linear drive working continuously. so, I need it to go forward, when it reaches the limit, it should immediately go back till it...
Hello CNCZonners,
I just joined the club. and I am absolutely new to cnc machining.
I have couple of questions.
1. can anyone please suggest a place to learn cnc programming (online preferable as...
