Ebay Chinese Routers (CNC3040) - anyone purchased one of these machines recently?

That's a bummer but at least it will give us an insight into how good the warranty / claim setup is from the Portsmouth guys if you can keep us in the loop ?

Think thats where some of the saving is, spindle on mine have had the brushes previously changed with too big a screwdriver.

Spindle driver circuit is on the very basic side, it will allow the motor to stall at low revs and has no back emf protection at all.

Hope your vendor is responsive, please do keep everyone informed.

Lid off pics, Yoo CNC controller:


spindle control;
Device numbers been scrubbed off the two power trannys, it does the job of controlling speed but a decent D.C. drive or change to VFD spindle somewhere down the road.

Paralell in breakout, now know why E-Stop does nowt, its physically connected to the probe pins ;-)
Being brought up on usenet not hugely fond of v-bulletin ,seem to jump from needing approval to not, to posts awaiting approval, dunno about spam situation but it don`t encourage new posters...
