f_armer: check my build thread for info on my $100 scribe setup
price went up because i added a $10 air regulator for down pressure :-s

my $100 scribe setup :D

i used an electric scribe to keep cost down. if we do more than a few scribe jobs i may update to an air scribe but for now i can't justify the $230 cost
parts: self made...

i'm setting a scribe up on our table right now. i have $80 in it so far. needed to order a regulator for down pressure, it should be here in a couple of week (from china). once i get it working, i'll...

any maintenance tips that you'd like to pass around? like:
cleaning the track/guides/gears?
z axis maintenance?
lubrication?

we just replumbed the barrels under the table so we can change the...

you probably cut a lot of plate in your shop, can you give me your thoughts on cutting a sheet of base plates?
i posted this over on pirate and plasma spider

have a job coming up; it involves...

i saw the drive fault in mach at the bottom of the screen
i saw red lights on the control box and saw it was off
i turned it on and all was good.
i'll check what lights are red and the temp next...

got a #3 drive fault today after cutting a tube.
it kicked out the dc and reset by turning the dc back on.
no problem, just fyi. only happened once.
which motor is controlled by drive 3?

mc: we'd like to wire stop buttons on both ends of the gantry and a switch on the maglok plate to stop the machine. does our machine have the inputs available to add this? i'd like to run the same 2...

thanks mc. rotary table cutting a lot better. this is what the pic above was supposed to look like
except the torch was dragging as you can see from the top segment that didn't drop out.
that was...

had to cut some flat plate today, so didn't get to work on the rotary head until late. i thought i had this rotary head sorted out. i pulled the cover off to check the set screws on the pulley. the...

i slowed the cut speed and voltage to 180 and 80 worked fine, warped the crap out of it but cut fine.

new problem today with the rotary head.
tried to cut text in a 3 inch tube, turned out like...

thanks for that, but no upgrades in our future.

i have no need to cut at those speeds.
just following the cut speed in the hypertherm manual.
what ipm would you recommend?

i was amazed at...

first time cutting thin gauge steel. 22 ga steel, 315 ipm, 120v; dross free cut.
problem is the corners should be sharp angles, like the starts, not radiused corners.
what happened?

i have the rotary head working fine now. use a small pump to run coolant thru the chuck into the tube to keep slag from sticking to the inside of the tube. inserted a few gcode mods: one M7 at the...

still working on setting this table up. working on a coolant pump setup so i can cut tube.

i'm using the rotary head on my plasma table to cope ss exhaust tubing for making h-pipes. i'm getting...

yes. i meant ipm. i also used fps which would be ridiculous.

honestly, i am impressed with how this table cuts flat plate. i need to post some of my success pictures on flat plate. (need to take...

my 48 fpm speed is rough calculated by timing the cut.

still working on the rotary table. right now my max speed is 48 fps which is half of what i have entered into sheetcam and mach3 profiles for finecut consumables. we have the acceleration down so low...

the rotary table is working well now after talking on the phone with matt. still not sure what fixed the problem. we still had some discrepancy when reversing directions, some were cutting some left...

thanks. i'll try those tweaks

no, i wasn't using the rotary post processor. am now

but when i do it swaps the axis's. i did a tube cutoff and instead it slit the tube lengthwise.
i rotated the dxf in sheetcam -90* and it cut...

not sure how to ground the rotary head, i assume grounding to the table would weld the bearings in the rotary head.
similar to welding on a rearend with the ground clamp on the bumper

this is the...

the cold weather is headed our way too. had to leave the water running or we lose water in the shop around zero.

i used the rotary program. probably a setup issue to lock out y axis. i did not...

tried the rotary head today with out any luck. loaded a cope program in the rotary mach3 program. the y axis took off, y axis should be centered on the tube and all cutting done with x and a axis....
