Thanks Ger. Will check my settings on the drivers. Not sure how much microstepping i'm using atm as i've set up the machine time ago.
Then will give it a try with pulleys.

Ok thank you.
I'm good at coding but no time to invest in studying trickeries to make a new device work on Linux CNC.
As a first thing I think i will just give it a go with pulleys and timing belts...
Thanks a lot Ger.
I think i can still squeeze out that torque from my nema 34s at 300/400 rpm, so maybe just the different leadscrews should work.
What about multiplying that with pulleys and...
Thanks pippin. It's 4mm/rev pitch. Do you reckon the 5i25 would be a good improvement by itself? That would save me 130 bucks.
I see, but i would be ok with the speed that i can achieve on the 1 motor axises.
I cannot get anywhere close to that in the x axis with 2 motors. Plus given the higher torque, i'm on direct...
Hi All, Here's my machine:

Since this video i've added a table with clamping nuts and some clamps, and a betterdust collecting system.
It's based on...
Hi Everyone,
I apologize before for the lenghty post, but wanted to include all the possible info.
I have a routing table with 4 Nema 34 motors with double shaft, 4 DM860A drivers, and the simple...
Hi Wend. Thanks. That is exactly how my setup is working. Now i'm wiring some microswitches for the limits and changing the skates bearings enclosed in some pieces of corrugated tube with hose clamps...
Hi James, thanks for your bit of advice as well. I saw that Gerry is present in a lot of 3ds and very helpful and knowledgeable.
A thing that you wrote lighted a bulb in my head. When you say:" feed...
Now it's 100% clear. I will also update my drivers / steppers combination then.
Thanks a lot.
Hello everybody. Great stuff here. My spindle now rotates at 24000rpm with these settings. But it does it only with the onboard keys controls. My inverter has an onboard pot which if i set PD002 to 1...
Thanks Gerry.
One thing.
How a smaller motor with less torque, can be more efficient than a bigger one?
Do they have a different torque curve?
My understanding is that stepper motors will give...
Oh my...
Well, the price to pay for lack of experience. I like my big and powerful motors though, i think it's mainly a problem of leadscrew pitch, which i will eventually upgrade after i have...
I'm pretty sure i can. I was filming a solution i'm trying for a dirt cheap cable management solution (scrap used cleaned bike chains get for zero bucks on a bike store) I was able to run the whole Y...
Sorry for not having specified. It's 20mm diameter. The motor's shaft is 14mm. Found some nice 14 to 20 couplers on aliexpress.
The travel is 4mm per turn.
Hi Alan. Thanks for the answer. Here's the label of one of my motors. Cannot really get the number you asked.
275824
Unfortunately i was in doubt on the size and motor type, so i went for the big...
I have built a big CNC machine with 4 Nema 34 motors. It's 1.70 meters per 1.50, and the gantry is moving via 2 synchronized motors. All running via Linux CNC.
It's a Longs Motor Kit with DM860A on...
Hey guys. Sorry that i've suddenly "dead" like that.
I've been through a lot, including modifying my garden so i can build a shed to use as a lab, big enaugh to fit my machine.
Also solved the...
Well. That says a lot. I consider the breakout board purchased on the kit, the less expensive component of the kit himself.
So i already knew before buying that i may have to upgrade it. First i...
Thanks Doorknob for your suggestion. This is actually my first build. I saw a lot of other people using this solution. Would you please explain to me in what measure the signal can be degradated and...
Hello everybody. I really need help before the 30 days from receiving period expires.
I bought this kit:
4x NEMA 34, 1600 oz in plus power units, drivers and breakout board.
I wanted to test...
Hi everybody. I'm in the process of building my 1st CNC router and i couldn't miss the main reference point for CNC enthusiasts.
