The 2.2Kw Chinese Spindles - Info, Setup and Advice + More

>because pins touched due to poor soldering

Hehe. Dean, the soldering was good, it's just that there was too much of good soldering..! ;)

Wal.

The old maxim that "the bigger the blob, the better the job" was NEVER good soldering

Scrupulous cleanliness is the key, a one molecule thick layer of grease from your fingers is enough to ruin what could have been a good joint.

PS Like, wow man! far out! That was a seriously good joint, dude.

Have you set the parameters in the VFD

[aprex]

Yes, even by hand you can hear a discrète grinding noise.

Think I might be buying another from the same place and sending the old one back for a refund

[AndyUK]

oooh you fiend!

No mercy when you read their answers to my problem; warrant y or exchange/refund, they're deaf...
I hope return address is the same as sending address (deuchland). Shipping cost could be a pita

This advice goes for anything related to CNC, esp electronics. This is the biggest mistake new builders make next to buying stepper kits.
Only buy when required because not only do you get a warranty when needed but electronics change fast these days and it's sod's law when you fit it you are already behind the times in technology.

Very sorry to read about your problems.

Clearly the ideal solution is replacement by the supplier or manufacturer. If you bought it within the EU you should have some protection (unlike our pommie friends since Friday ) and it may be worth checking if your method of purchase offers any protection or insurance.

If they refuse to help you then there may be people on this site with experience of dismantling and repairing these spindles who can advise you. It sounds like a bearing problem which is something you may be able to repair yourself with the right help.

Thanks a lot Kitwn, you're right, speaking with my seller makes me understand than it will be a DIY story...
Well, little humor story just for fun:

Just finished my CNC and started the spindle; this one makes a very bad bearing noise. I can upload a video for you. Very disappointed...

Dear friend,
don't worry,our engineer tell us ,that is no problem, and he said: when the spindle bearing in the high-speed operation, the start state is unstable, may be possible to produce a variety of noise, the noise is the product in the transport process in the accumulation of grease caused by the side,until the grease dispersed after the spindle no such, you can use it ,
Thanks
Kind regards

Cher ami,
Ne vous inquiétez pas, notre ingénieur nous dit, ce n'est pas un problème, et il a dit: lorsque le roulement de la broche dans l'opération à grande vitesse, l'état de démarrage est instable, peut être possible de produire une variété de bruit, Le bruit est le produit dans le processus de transport dans l'accumulation de graisse causée par le côté, jusqu'à ce que la graisse se dissipe après la broche, vous pouvez l'utiliser,
Merci
Cordialement

Dear friend,
I don't think, it's a grinding noise, when you turn the spindle by hand you can hear a grinding noise. Even when you run it at 6000rpm. Do you have a mail address to upload you a video?
Thanks by advance

I'll upload the video on youtube and send you the link later.Best regards.

Dear friend, https://youtu.be/pfNIaMwcSyo Just checked of course, my wiring is ok. Each minute of running becomes worst and worst. Even the speed is not stable, a faulty bearing I think.It's clear for me, this one is defective...
Best regards.
