Re: X axis to heavy???

Jerry, I'm sorry, but I just saw this. This looks like there may be a repeating (consistent) problem with an axis, such as a miss-positioning error. This can be something like a non-precision pulley or sprocket. I had the same thing on a smaller machine of mine that was caused by the cheap lead scre...

Re: constant feed rate analog laser

Yes, those setting are what I use with my DAC and Mach3. Tony, the sending of steps by your gcode controller (Mach3?) will blend axis commands when the commands are on the same line so that all axes arrive at the commanded point at the same time. This is why the X/Y axes slow down with large Z moves...

Re: X axis to heavy???

Jerry, Please reread what I wrote. I said that steppers are not likely to cause wavy lines, without losing steps . Steppers do not fail from an excess load, they simply lose steps. Maybe over time a heavy side load might wear out the bearings, but I think that is highly unlikely in your machine. You...

Re: X axis to heavy???

Jerry, Steppers are not likely to cause wavy lines without losing steps, and your images show no signs of lost steps, rather they looked like loose belts/friction/sticktion to me. Changing electronics, software, etc. will not make up for mechanical issues. I suggest you switch to testing with vector...

Re: J-Tech Shapeoko Laser Kit

Well, maybe after I get all the Badger stuff done. :working)

I'm seriously thinking about setting it up with the shorter rails so I DON'T have to add on to my porch. :$)

Still undecided, but really waiting on better weather.

Re: Smooth Stepper

:respect)
Jerry, you do what you've done to tighten up your machine. Good job.

Actually, click on Full Editor and Preview just below the quick reply box.

These last tests look much better. Now you can go back to testing with smaller pixel resolution settings if you want.

Re: Smooth Stepper

Jerry,
You are making progress. But the 45° streaks should not be there. Please run all 4 angles again, but at a pixel resolution of .015.
John
