once you redo your steps in mach you need to tune the motors, change the vel. to 60 and accel to 15 and see what happens, you know when you change the vel. and hit the tab button you can test it right in motor tunning by pressing the up and down button, then when satisfactory, save that axis and set the others.

joe changed the jumpers to 1/4 stepping ms1 and I don't even get a response anymore from the motors.. sparky tried successfully on ms1 @ 1/4, but then again wouldn't 1/4 be worse for me than 1/8th anyways?

you will not see a difference cutting wood at 1/4 steps, most people use 1/4 steps on their board. i have even used 1/2 and still works good.

Then leave it at 8000 on each axis and change the microstepping on the board to 1/4 (jumper on MS1)

apparently 1/4 doesn't work then, have to email xylotex maybe its faulty, switched back to 1/8 th will fine tune but cut tomorrow, too late to cut my family will disown me if I turn on the router lol

well now I have a compromising situation, my z is apart now, took the motor off, the backlash assembly nut (top one) came out and is spinning loose on the rod and now its tight against the bearing and I can't get the rod out. damn...

[bp092]

nevermind, got the thing put back together after fixing the backlash and it runs better than before, phew!

I was going to sugest to take a picture of it. you need to get a camera, get a 3 meg. pixel for 80-90 dollars, walmart or other places. some will do video also.

I have a 6mp one but its not video.. anyhow, just ran bullshead and david again, man is the quality shotty, but it was taking most of the stuff in one pass and plunging a lot harder than I would have liked.. I probably A. ran it too fast and B. took too much off in each pass. Will take pics now and screenshot of vcarve readout of my settings to show.

okay here is bullshead again..



Need to get a dust collector hooked up

Sapele cuts nice though, not much small airborne dust, just chips.




It looks perfect, but it isn't hardly, atleast I don't think so. I'm not dissatisfied, this is what I want, because now I know I'm doing something wrong and I can measure the accuracy in quality. Check out the full res. linked below to see the detail. I took it without a flash so mind the slight blur, the flash washes out the imperfections. I drew red lines by the marks. It was pretty consistent, like little bumps as if there was vibration on the gantry or z or everything as a whole. I'm not suprised, I can see it as the machine jogs. Also occasionally it bumps into something too deep (maybe a 32nd" tops) and marks it up on some letters. Any thoughs?

Almost all digital cameras have video capability now, sounds like you need to get the manual out.

I was just thinking about that today for mine, I'm getting closer.

No, sorry. I have a nikon DSLR, it's manual digital and also fully automatic. I used to have but sold my fujifilm s5000 which did pretty decent video. I will be able to get video though next weekend or next week. Will help I'm sure to be able to listen to my machine and tell me what it sounds like. Right now I'm just winging it like many of you did when you first started off I'm sure.
