What do you really get for a $350 desk top engraver ?

that was an easy enough fix and all is working good now. i think i have everything dialed in about as good as it's going to get with this old computer. everything seems happy at 400 IPM on the X and Y and at 250 IPM on the Z. i don't get any warnings at these settings.

just something to share with everyone it looks like i got the cables under control pretty well. i have power to the VFD but no control with Linuxcnc at the moment. i have my home switches mounted but have to get them wired in at the enclosure side.
CNC first real test of movement (youtube.com)

 

this machine needs an enclosure. i did a little bit of cut testing and had to stop because i was getting peppered that much aluminum machining is not going to be an issue at all i had it pulling cuts at 250IPM and was nowhere near any limits.

No video = never happened!

i was not doing anything exciting enough to bother and honestly this thing could destroy some material and make a huge mess with out some way to keep it contained sorry more prep is needed before i let her rip full blast i have some flashing that i can skin a frame up with i probably won't have any time to get into anything serious till this weekend.

since i have linear scales around and a spare DRO i wanted to try this opposed to a dial indicator reading over a small distance. it worked really well. i was really curious about how accurate a belt is over the rolled ball screws everyone uses. over a 10" distance i was able to dial things in really close and test to see what is going on in the middle as well. i think if memory serves me well a rolled ball screw are only accurate to .003 to ,007 per foot as far as lead accuracy goes. these belts float around between 0.000 to .002 over 10" and i don't need any backlash comp either. the glass scales worked well for all this.
