Okay, so, here we go, I got a little discouraged over the past 2 weeks trying to sort out my issue of being off by an 1/8th. Ive been double checking everything and i must be missing something crucial.
Here is a picture of the auto cad file of that darn puzzle piece that wont come out right
I re calibrated the machine after cutting a few pieces changing a variable each time, (distance between motors, COG, Gcode, number of passes, etc) so i recalibrated and cut a diffrent piece because i thought i would solve the problem. I cut a box with notches to join the sides. And it came out Great!
Upon further inspection i realized to my utter confusion that the outside dimentions are off by an 1/8!? The rectangles are off by an 1/8 but the notches and tabs that go into the notches are dead on, (well + or - 1mm which is acceptable for now)
My machine was cutting at one point plus or minus 1mm but now off by an 1/8. I dont think ive made an significant changes. It all went to the dogs when i re calibrated it.
Oh and all the cuts ive been doing are in the center square of 2’ on the Z and 4’ on the X axis. Where i understand it should be the most accurate.
I adjusted the CoG further to keep the sled from lifting (it was doing it slightly) still not 100% fixed. Ive adjusted the feed rate to 250mm/M witch seems to help. Any ideas how to eliminate that? And what feeds are you all runing at?
Im aiming for plus or minus 1mm thatd be great but in the mean time, i cut a tree for my mom cause that doesnt need to be super accurate.
All the outside dimentions are off by 2/8ths now arrrggg. But one of the notches is dead on and the other is 1mm out. I dont understand.
I am by no means a mechanical genius like you but id like to get it pretty accurate.
My machine is precisely inaccurate, any ideas on what it coule be?
