Hello there.
I measured by backlash and it is about 0.007 mm. So I tried to compensate it in Mach 3. Backlash movement (0.007 mm) works but that movement counts in DRO while moving for example X...

Good man, I also changed my PC and problem was fixed :)

Thank you man. I will check it out. I just downloaded Vectric Aspire but didnt have enough time to test it. I will check meshcam too.

Thank you!

Dazp thank you!
Very nice explanation. I will try all of that this weekend, cant wait. Sure I will report back here!
Have a nice weekend!

Good! Someone also suggested me Fusion 360, I will check it out on YT. Thank you!
I also found a combo using Solidworks and Artcam, what do you think about Artcam?

I will check it out!
Thank you for suggestion!

So I wont waste my time for those settings, I will just set to 2000pulse/rev, test it if its good and leave it like that. Thank you!

Thanks dazp, I will try 35khz setting and see how it rolls. About previous posts, should I limit the amperage on driver by peak or RMS? For 5A motor I should set to 4,9A peak and 3.5A RMS or should I...

Hello people.
I am electrical engineer and have a little experience with SolidWorks and NO experience with CAM softwares.
I have 800x800mm self made CNC machine and plan to use it for woodmilling...

Interesting, you've got the point. I will then just test microstep setting at 4, 5, 8, 10 and see how motors run then.
Thank Craig!

What microstep settings do you suggest on my DM860 drivers to be? 400,800,1600,...? And why ??

Good to hear that.
Then Ethernet controller is the way to go. First I will finish several thinga that i need to do if I want my cnc to start running. And then comeback at controller and update it.

Craig thank you, i will write down those controlers and stick to buy one of them if i will plan in next weeks. Now i got my LPT running great for now so lets give it a chance.

Good thank you!
I fixed the problem by running my cnc from another PC. LPT on previous pc has some issue. Now with "new" motherboard, motors are running great as f*! No more strange noises, no more...

Ye I know, I am using trapezoidal sorry, but theres not really much of friction, I nicely set the positions of the nuts and leadscrews. Maybe i will replace em in near future with ballscrews. I will...

Thank you!
1. Good, I will try to replace motherboard with processor on it (i have one old pc laying around at home) and reinstall everything, do you suggest WIN XP, SP2 or SP3?
2. Do you think...

Thank you.
Motor heat is ridiculous, they are very hot IDK why btw. I have 4mm and 3mm on Z axis pitch screws.
Good I will try this setup you wrote once I get my motors running smoothly.
Yes I...

Thank you, I already tried many different settings at stepping and amperage but motors runing strangely no matter I change the settings.
I think the problem is at PC due to unstable output...

Hello people.
I have an issue, mine stepper motors not running smooth, its like PC is not sending pulses to motors continously. Its like there are some delays at random times between pulses.
Also...

I took the photos of the brackets of the working table.
They are 20cm x 20cm x 20 in three ways. They will be screwed on the bottom of table (with other words: table will be screwed on those 4...

No, at first I wanted to put that X-frame but its not flat as I wanted.
It will be just aluminium table without steel.

I am also worried about flexing those guides without supports yeah...

The height adjusted table will be on four round linear guides. Those guides are located in all four corners as you see on the picture (vertical).
On the table will be adjusted bearings 8 bearings...

Hello everyone.

I am asking for some advice for building working table for CNC made of aluminium profiles.
My workings surface will be 780x780 mm.
So what do you recommend me to do, which...

Hello!

I sold my kit of motors, drivers and power supply. So now I am looking for new kit - more suitable for my application.
Please recommend and help me with suitable kit.

What did your...

You are right so my stepper drivers has options of resolution of 400 pulses/rev to 25600 pulses/rev.
So there it should not be a problem of low resolution.

If I go with 400 pulses/rev and pinion...

OlfCNC and what do u think about my last reply?

I saw alot of people used stepper motors for CNC and get high movement speeds like on that link:
https://www.youtube.com/watch?v=TcWSiFnfuAo
That guy has rack and pinion.


I tried to power the...

Its a screw drive in all 3 axis.
I will be moving around 20 or 25 kg that is 55 pounds.

The moving speed of the machine was meant to be around 25 cm/s that is 10 inch/s or more.
The screw drive...

Yeah.. I found that expirimentally formula of Voltage is needed to be 32 times higher than square root of inductance in mH. But I ordered a kit, all components came together..
Im making a CNC, kinda...
