Welcome to LaserBits The World Leader In Laser Engravable Products and Training

450 is emergency stop, is it sitting on a limit switch or something else? are you just wiring the limits and home switches then? I believe the factory just used sjo type cable for those switches.

I paid around $7800USD for that same size machine delivered with rotary attachment. I would gladly buy another if I could get it for 5k...
Either way 12k is too much, especially for a used system.

cool :)

you have to pull the rear cover off, where the cable goes in. that will give you access to the encoder and tach. dry compressed air works well to blow out the buildup of carbon from the brushes. the...

About the only use for the air pumps that come with most of these lasers is to add air bubbles to your fish tank. I have my lasers plumbed into my shop air and can adjust the flow for any...

you have to edit the parameters to allow 'full dos filenames'

i did see the other post thanks

and the winner is???

well the Monarch is gone(long story) but I added the Clausing lathe that I put the cent7 control on.
also added the 2 rabbit co2 lasers, a small surface grinder, and a bunch of other stuff not worth...

i would pull the motor brushes and clean and/or replace them
you can also swap cards and see if the 'twitch' moves to another axis

not all G-code is created equal...you would still have to work with the files to make sure they would run on your machine.

I use methanol. Enough drops on the lens to cover the surface, lay lens paper on top, wait for paper to soak up methanol, slowly drag until end of paper or methanol is gone from lens. Do not reuse...

if you swap servo drive cards does the problem change to the other axis or stay where it is now?

One thing to think about is those machines didn't have the quietest head with the variable drive, back gear, motor, etc. There are many things that could be making it louder than normal. I would bet...

Yes that is normal, the machine looks for home switches, backs off of them and then moves back towards them to find the marker pulse on the encoder. Usually you will set G54-G59 for work piece zero...

i use a mold release agent liquid that you brush, spray, or wipe on before cutting and it works pretty well. apply it, let it dry, laser it, and wash it off. :)

you usually want to get the rails and blocks together and not just put new blocks on old rails

some of those bearings had marks that formed a V you line up

I'm not sure about the optic mounts in your machine but if they are built like all the other asian machines I have worked with they are absolute junk. I think the only reason people don't complain...

wow...where to start

corel plugin that actually works right and with newer revs...
more cad like drawing options built in...

i had a long list but im having a rough morning so i don't remember...

what servos did it have and which version of control?

you would also need full dos filenames turned on for the control to read a file that isn't in the OXXXX name format

the one in the picture is a Milltronics Centurion 4 control. what makes a Milltronics a Milltronics is the control. they got there start by retrofiting iron like whats in the picture with their...

I would say mill for sure and no question if you plan to CNC it in the future. you can make most any round part on a mill but thats all you do on a lathe(standard 2 axis that is). I have made lots of...

if the budget is not an issue why would you replace an industrial control with mach???:confused: If i were you I would look into replacing the cent5 with a cent6 or 7 or just repairing the 5...

your RPM was too high...no coolant I assume...did you have the tool tight enough(no slipping)
you should always lock the axis
the problem with used materials is you don't always know what you...

i made one of these out of 1/8 acrylic on a laser machine here at the techshop in beaverton
the wife loves it, we spent 2 weeks in Paris for our honeymoon so she said I had to make this model:)

they are DC

only if it became 'excess error'(following error keeps increasing not staying steady).
if the following error on x is .05 and .075 on the y it would still run without errors and it would point to...
