Amos, have a look at the shapeoko wiki. Some really helpful info.
Hi amos, been going through a similar sort of thing. There are so many variables at play that could be causing the problem. Just out of interest...
I don't seem to be able to see your picture. Going through a similar sort of problem, although my machine is not an OX.
Thanks for the thought FRIDGE. Yeah, rack would be awesome. I think it would definitely help a lot! It would mean a complete redesign though. Not...
Hi guys, back again. Well, I have been cutting and making stuff, but not quite there yet as far as accuracy goes.. Still getting slight deviations...
Today is a good day! Installed the dual belt and what do you know, backlash all but gone. The machine is finally cutting like it's supposed to. :) :)
Finally got everything as square as I possibly could with the limited tools at my disposal. Went for another test cut to find that the cuts were...
@Gray, you were spot on sir. The problem is in the gantry construction, i.e. Ever so slightly twisted towards the centre. There is a length of...
Sorry for the delay. Work, sleep, all those kind of things getting in the way. Decided to check, or should I say re-check the squareness of...
I'll give it a go. Report back in a couple of hours.
Thanks Tweaky! I think we are getting somewhere now..:) Guess I'll be pulling it all apart to try and find that **** flex, of which there is a...
here it is. Cleaned it up a little when I rotated it. Took out one of the circles and one of the V's. Hope you find the culprit in there.
You have a very good point Tweaky. I noticed this after I did the 90 rotation. Just getting the gcode out of the computer now. Will post it in a...
Just so you know the gantry is the y axis in this case. Currently I have a 1200x600 bit of MDF that I've levelled as my working area for the...
Still think the y axis is the one with the most backlash.......:banghead: Tried tightening the belt, checking for binding. No dice....:banghead:
Thanks Nick. It's driving me insane. :) Well, I decided to rotate it all trough 90 degrees to see what the difference was. Not sure exactly what...
Ok, so I did some testing. Changing acceleration, rapid and feed rates for every lot of six squares. The numbers at the top right of each lot of...
Nema 23s (269 Oz-in) all round. Gecko G540@48v.
Loving this idea. Been thinking about something similar driven with a stepper and an arduino. The idea would be to have a number pad/keyboard...
Hi Larry, not sure if I quite follow what you are saying. Are suggesting I go over the motor tuning again? If so what recommendations do you have?
