I´m Using deskcnc, had a try with mach3 but the problem is the same with both software. had another try today and got to the coclusion that circles are like egg shape tilt at almost 45 degress, not...
Thank you again,
i guess i´ll have to replace the encoders soon then.
when i say the machine shakes a lot is because i get hard stop on corners when using gcodes from cam programming. it gets better when using the smooting parameter but than circles are not circles...
thank´s
i´m using 2000 ppr encoders. that is close to 0.001 mm per step move. yes it has something like auto tune but i still have to mess with some parameters to fine tune it.
if using the...
Hi All,
I do have 3 axis hiwin ac servo setup on my mill. I have deskcnc board with the servos running in step dir . hiwin servos has a smoothing parameter from 1 to 500. machine runs smooth...
Thank´s a lot.
you are the man. so i´ve this chinese power supply that shares the common with the - output, it is not isolated but i´ve used a isolation transformer on the power supply mains input. i dont think...
Right on it! any reason for that?
there was a isolating PS , but it was a 380v input so i have exchange the original Ps by a chinese 24vx14 amps Ps and installed a isolation transformer to the mains input of the chinese Ps.

Im retrofiting a votan cnc machine, im trying to use the existent controll panel (box) and all the dc control wiring that includes all of the machine relays,solenoids etc exept for the ac stuff.
...
Yes, i´m doing it :-)
i´ve figured it out already. its a spring return.
the pump only runs to pressurize the system, there is a accumulator ( nitrogen) . there is a preassure switch on the pump...
Hi All,
i´m retrofiting a Wotan machine center, 3 axis mill . the manufacture has gone out of bussines and i´ve got this machine used with no controller . I´ve new servo drives on it.
the...
thinking about to get one, but looks like it´s one of those never ending story.
I´m wondering what other manufactures avaiable on the same system?
I´m using a minimill motor for a long time...
10cm/sec = 100mm/sec. = 6meters/min. are shure you´re having that feed speed with a 25w laser? how thick is the acrylic?
Yes it´s extruded, i´ll try cast if I can find a supplyer for it.
tem00 means you have a round spot that tapers to a sharp point.
it´s the best TEM mode to cut acrylic. Some chinese made tubes does not meet this, like the one I´ve :confused:
If you want to...
first check your laser beam quality, it should be a perfect tem00.I had the same problem with my laser and I´ve found out that´s becouse of poor beam quality. it´s more like tem10 ten tem00.
Well,since I´ve got answers looks like no one can get a nice finish o acrylic, any way I found out I´ve a bad laser beam close to a tem10 mode, never mind.
Yes, depending on the position you mount your tube it will trap air inside near the water output, this will grow up to a large air buble and crack the tube. I had to rotate the tube till find a...
If it´s a chinese made tube then it´s normal to happen.I´ve seing some tubes gone like that for no reason. I´had a problem with my tube, it broken the inlet water chanel that cools down the back...
Hi All,
I´ve made my own laser cutter using a 80w chinese made laser tube. I would like to know at what speed are you guys running your laser to cut a 6mm acrylic and have that flame polished look...
Hi All,
I've downloaded a laser calculation software from synrad and the cutting speed I'm getting from that is almost twice as much from what I'm getting from my chinese laser with the same power....
Hi Mike,
I've a 40w chinese laser and I can cut up 5/16" in one pass but speed is darn slow.
0.1" acrylic at full power and 15"/min.
0.125 Acrylic full power at 11"/min.
If you want a...
I think at the moment only testra can do it.I'm also looking for a controller that can do both at the sametime.
You're right, switching linkmotion from raster to vector is a pain.I've droped it...
I'm using the laser W power post processor,it works ok for vector cutting but I can't do raster engraving, Carl is working on a raster engraving postprocessor but it's not done yet.
Also I'm using...
Hi All,
I'm building a cnc laser cutter and I've a question about how to wire the laser tube and P.S.
I've bought what was supposed(that's what I've paid for) 60w laser tube from a Ebay seller...
