6040 router

I wish the Chinese would catch on with these mass produced CNC machines ...it's a chore for the average bloke in a shed to fit homing & limit switches after buying the machine - you'd think they'd have that covered off by now! Some of the control boxes I've seen for the 3040s at least have sockets to plug your self procured/fit switches into, but this is one of the control boxes that doesn't....not insurmountable, but really....tsk, tsk

From a newbie to CNC but not buying equipment from China, must admit to being very pleased so far with my 3040.

Bit like dealing with clients , its a case of expectation management, did a lot of reading of threads here and on cnczone and watching youtube videos.

So before it arrived , had some expectation of shipping damage, seller obviously learning that one , have enough polythene foam to practice foam cutting till next decade.

Aware that the drive electronics are almost disposable, air cooled spindle drive is basic and the stepper drives are apparently suicidal.

Spindle is a `refurb` and may last forever or till next week.

Previous experience of Chinese vendors has to be honest been very good, delivery often faster than a UK based supplier and Chinese sense of honour has meant they have looked after problems well, dealt with more shady Euro vendors than Chinese ones, but very interested to see how poster with ill spindle is looked after.

With a burning interest in learning more about CAM and a limited budget, Chinese vendors have made starting out possible for me. Alternatives at the sub 1000 GBP level would have been a secondhand Roland PNC engraver, really don`t think they will cut alloy no matter how much time have to wait ;-)

Interest , at least intially, is what can it make rather than how it is made, shortage of time, skills and tooling made self build first off not even worth considering.

Don`t think these machines are taking work away from manufacturers or operators of bigger machines either, quite the opposite, ability to develop and test prototype and very short run parts myself means can find what will work in the market for me, when need more than proto or very short runs will be popping up in the RFQ section looking for someone with a bigger machine to make them.

Orginally started posting to say the connectors used on the Yoo CNC boxes are CB microphone connectors;

I've a 6040 router that has a dead driver board so I'm planning to replace it with a Gecko G540. I have a 48V supply I was going to use but wanted to find out the specs of the motor. Nothing useful from the supplier other than a 3A current rating. Despite an extensive googling, I'm no wiser.

Here's the label on the motor

Finally found time to work on this machine.
I built a new controller using a Gecko G540 with a 48V power supply. I've still no idea what the inductance of the motor is but it runs well with no overheating. In trying to track down an annoying roughness (motor tuning was to blame), I found a couple of mechanical issues with the X and Y axis bearings. Nice and tight on the ballscrew but loose in the endplates. The motor end of the ball screw has a single bearing and the other end, two bearings. None seem to be angular contact type. Lacking a working mill, I'm going to put a shim around the bearing to make it a tighter fit. I'll check out the options for fitting better (angular contact) bearings to the existing end plates if possible.

hi i have the same 6040 cnc and would like to ask what is the setup in motor tuning step per mm that you put in the software thx for your help

im using mach3 and no clue what to put in motor tuning
