What do you mean ?

Spent the whole day today drilling, threading and screwing. Spindle and new x axis guides are on their way.

Have all the parts except stepper and ballscrew mounts cut. Drilled all holes for trucks. Few poor pictures:

How can I change the...

Will do sir :) I was planing to do so, just a little tired of sketching.

Good to know. I make it my plan then.
Received the parts today, outer package looked like everything inside will be destroyed, but I can see no visual damage. Everything fits together, quality very...

I hope I'm getting somewhere. I went back to a earlier design due to I can't find a good way to mount the ballscrew assy for y. Anyway, I think I like how it looks now. Some key changes :
changed...

Thanks for the reply.
Have been looking for new ideas and drawing last two evenings. It's starts to get complicated to figure out how to make it work, but I came up with something.
Machine starts...

Hey wizard, thanks for comment.
I'm looking at 1.5-2.2 kw spindle. When I look at it again, it really looks a flimsy. Do you think it is better to reverse the rails/trucks and make the tower 40mm...

Got electronics the other day from longs motor. It was packed very well. Everything seems pretty good quality, i even opened the controller to have a look and it looks good. Connected everything...

Dylwad, there is a problem associated with that. If I lower the blocks, I loose the same amount of travel. To regain the z travel i would need to rise the gantry. I'm kinda leaning towards the...

I will be using drivers from china, basically I will have a Chinese machine :D Here is the link Stepper motor driver DM542A, 4.2A, 18-50VDC, CNC New | eBay
I will update when I start the build.

Hey fuper, your web seems to be down. Your machine looks great, considering it is your first build. Next one will be much better. Some years ago I tried to make a router the parts I had on hand, it...

Hello guys, thanks for input.
The idea of changing z axis seems good. I redrew the axis. I will consider that, or some stiffening on the spindle plate. It also seems the same amount of material.
...

Hello everybody,
I'm starting on a router/milling machine and would like to hear some tips from you. I learned Solidworks and designed the machine here first.
It will be used on different...

Thats exactly what I needed to know !

Thanks guys.

Mcmmach, thanks for reply.
I allready know that torque more at bigger rpm. I think all (or most) of factory tests are at nominal voltage. If I connect a 2 volt stepper to 20 volt controller (pwm or...

Hello everyone,
I have this question: If run a stepper on higher revs and increase voltage, will the torque drop or stay the same as in lower rpm ? What is the practical rpm range for a stepper...

Great

Well, all I can find on theat page is component layout and schematic. What about pcb files for toner transfer or something..

Thanks

Hi James, where Can I get pcb files of linistepper ?

Thanks,
Robert

Hey guys, I've got some 3-phase stepper mottors and have a source to get them cheap. I'd like to use them, but i cant find any control circuits for them. I think i can run them with software like...

I hook it up between chopper's center tap and motor. It's a simple multimeter which measures voltage, current, resistance, capasity etc. Well, steppers do spin but there is not much torque

Pminmo, I still have some trouble. When I connect the motors, my multimeter shows only 0.7 amps instead of 2.5 A rated. It cant fall that much one wires. They are 1 or 1.5 mm^2 and about 1.5 meters...

Anyway, what does jp1 on chopper driver do ?

Pminmo, it was -35 to + 35 volts. The diode removes about 30 volts from the bottom and now everything runs fine, but when I measure current with my multimeter i get 1.5 amp reading instead of 2.5...

Hey pminmo, nice soldering. Mystery solved, I scoped the drain and found it's amplitude was about 70 volts ( before it got out of bounds) and realised it was the induction of the coils. After that I...

I looked at other channels and they are similar to the first one. Something's not right here. If i get that swing on the gate, why would'nt it open ? What else can I do to help solve this mystery ? ...

Atleast that is what the scope shows. Drain and source graphic is not as nice as gates, i think it should look like gates but with amplitude from 0-35 volts. Maybe I fried my fet ? I still can hear...

Here are two pics , gate and the source-drain. Division is 10 volts, zero set to -30 volts ( to see better) , so as I can see amplitude on gate is 12 vots. Drain and source "visuals" are almoast...

I'll try to. One end of coil (or resistor) goes to center tap and another goes to boards negative.
