My first plastic engraving project so I used the PW's array text feature to make 'badges' the text moved in well, the tool depth seemed to work OK, got a decent zero at the surface of the plastic instead of using the z-stop switch/auto-Z,0.
First 75% of the file seemed to cut well, the 60DegV single flute seemed to cut the two layered plastic fine, left clear text and all seemed fine.
At about 75% I hear a Z step 'growl' on the Z up from letter to letter and next the Z has been readjusted so the cutter won't touch the work???
As I was doing 110 1" x 2" tags in a 24"x24" sheet I'm hoping someone here has seen this and knows what I've done wrong?
I had taken off the dust skirt since there's little chip scatter, and it seemed to resist Z,neg moves since the tip is so close to the spindle collet. I wanted to get the file 0,0,0 as close to exact as I could.
I'd had this (Z stall or loss of vertical reference location) happen when doing the file earlier as an 'aircut'. At that time, I manually moved the carriage off the table's center, exercised the Z up and down and there was a definite stop - only had about 1" vertical travel somewhere in the middle of the Z carriage range of motion. At that time, an hour earlier than file cut error, the K keyboard control 'page up' and 'page down' keys wouldn't move the Z Carriage very far before the growling stalled motor sound.
However, after the third manual keyboard up and down; the Z motor moved past the 'jamb' smoothly and I went ahead re-zeroed and cut the file. All was well until about the 3/4 mark- then the same Z noise, and re-set reference?
any advice welcomed,
How do I get back to the location I was in the file? and
Why did the Z loose it's orientation?
Am I moving the Z to fast, I'm using default Quick Text parameters?
cheers,
Kevin Morin
