Hi,
I am in the build phase of a DIY wood router.
- Sized for 4 x 8 sheet
- model airplane wings
- sheet plywood
- Various other hobby things.
This is for hobby use for routing wood and foam. I have an idea to also use it to improve my drilling results as it also incorporates a drill in the Z axis. (not a spindle, a hand drill, so not perfection use, just better than I am by hand)
Drive Method
- Tried to do them all the same, but in the end, they might all end up different, but most likely belt and rack and pinion.
Motors
- At this point, steppers running open loop. I have some linistepper driver kits already, but am open to options if other methods are significantly better, and I have the budget.
Question
Regardless of what method is used, there are always imperfections and non - linear areas of a drive mechanism. For example, even high end ball screws have a rating for "accuracy per foot or meter", and a belt has even larger errors, most likely, not consistent over a 8 foot distance.
I read the mach III manual again last night (yes, I am a beginner) and found a setting to "fine tune" a local section of motion for a movement distance, but I wondered if there is a method to "fine tune" sections of the axis. Example, if I can manage to borrow a very accurate meter, can I somehow profile the axis for these imperfections continuously, or over say 10 regions of the axis ?
I realize that my work may or may not need this, it is partially for my own learning.
I am sure this has been asked before, I just could not find it in the many pages of threads or the manual.
Feel free to just point me to the right section of the manual or an existing thread.
Thanks a lot
Harry
