My Cheapo Chineese 3020t mini CNC Build (more like improvements) leanring all the way

Right chaps,

had a bit more time playing with the machine, ive got the motion speed set pretty low, feed rate set at 200. But it seems to be struggling with right angles and sharp points, it seems to add a small radius in these areas even though on the preview on the software there are clear points.

Any ideas?

Just had a quick read, ive now changed the motor speeds in my planet software from 500 to 200

seems to have sorted it i think, bloody slow now though lol

Sorry, missed that you was using Planet CNC software. Check this out http://forum.planet-cnc.com/viewtopic.php?f=5&t=1271 (no promises!)

managed to speed up the motors to 500, but changed the blend value to 0. Machining fine now, but a bit stop start on curves

not much of an update but ive begun sourcing parts for the new extraction system and also the new enclosure. Ive tidied up my tool bench and moved it from the back wall against my booth which has free'd up some more space. Also got a big screen dedicated to the cnc stuff







I have made some small holes for the machine wires to drop neatly through the base of the enclosure so it is nice and neat, will be going to screwfix later to pick up some odds and sods for the extraction system. Im happy with the setup so far :-)

small update with the new setup, extraction system is all done, just sorting the power supply to the rear fans, I bought a transformer but its ac - ac instead of dc so need to get another one then that will be able to power the fans via a variable speed controller. small progress but starting to look the part
