    Word of warning on the VFD that is not a Huanyang VFD it's copy. So don't try setting it up from any settings found on here because they will relate to huanyang which is completely different.

    I have fitted one in the past and it worked fine without any troubles but I wouldn't and won't fit anymore because the huanyang are much better, which is saying lot because they are not exactly top quality however they just do the job.!

    If can send it back then I would or at least complain and ask for some compensation which is what I did. They refunded me some money because all the pictures showed Huanyang VFD but I think they have changed the pictures now so maybe nothing can do.?

    The thing is that it doesnt say that it is huanyang in the advert, so i dont know if i can say it now for the seller. The only difference i see is the colour of the warning sticker, to which i did not pay attention at all if that is the sign of huanyang.. Here is the one i bought:

    Yes the case is exactly the same but other than that it's nothing like Huanyang. Completely different setup and if you look all the I/O terminals are different.
    If I remember correctly the Analog 0-10v isn't isolated from rest of I/O. Also No on board Relay and possibly only 12V output not 24V but could be wrong on this it's been good while now since fitted it. It also won't display RPM only Frequency and Current I believe.

    But like I say it worked fine and believe it still is so wouldn't be too concerned. But I'm fitting huanyang Vfd's all the time and can tell you 100% it's not huanyang and didn't want you trying to set it up like Huanyang.!! . . . . Only the case looks like it the rest is nothing like huanyang.

    plus the legends on the front panel are all different. But don't worry about it, It will work fine just make sure as Dean has said to only using the parameters in the manual you should get with it.

    Can i expect from equal aluminium angle 90 degrees on the outside? I was so sure that is 90 degree, so even did not check it when was buying it today. Took it home decided to check the squareness it and it is less than 90 degress.. Tried to google it out, and here is what i found: "A 90-degree angle is certainly the most commonplace for aluminium angle stock, but there are products which have less than a 90-degree bend".
    So maybe i was lucky to get that with smaller angle or it is common not to have proper 90 degrees angle? I saw someone was using those angles in this forum to bolt together the frame, wondering if there were some issues with that?

    Hello. Its been a while after my last post, but things kept moving a bit. Since that got aluminium plates, simple ones drilled and and tapped myself , more crucial parts like gantry sides, z axis plates, motor mounts will be machined by our guru JAZZ.

    when i was assembling bearing blocks when i put together bk bearing i have a gap between lock nut and pulley which i did not see anywhere in peoples threads, and i am thinking maybe i assembled them wrong ? everything is tight and there no playClick image for larger version.

    Other weird thing is that i could not put all six screws through balscrew nut into its housing, holes doesnt align poperly. Once i put one screw i could not put second one because it just doesnt catch the thread. I have only one ballnut which took all 6 screws with no problems. Click image for larger version.

ID:	20459 And i thought that is not a big deal i will just open the holes a bit more, but i couldnt do that because the metal is very very hard. Then i noticed that the "Good" ballnut has tapped hole in it. it must be oiling point, all other ballnuts doesnt have it. Any one had issues like that? I probably would need to contact Fred to see what he will say about it, I bought all components from him. Thats how it looks for today Click image for larger version.

    Looking very tidy well done!

    Gap between lock nut and pulley:
    That is not a problem. The lock nut is used to pre-load the angular contact bearings inside the bearing block by pulling the shoulder of the ballscrew against the bearing on the other side. If there is no axial play and they turn freely then all is well. The pulley is only held onto the shaft with one or 2 grub screws so it can go where ever you need it to align it to the belt. It doesn't need to butt up to the nut to function.

    Ballnut/mount hole alignment problem
    I've always made my own ballnut holders/plates, but for my current build I bought some of those C shaped ballnut blocks that you have in the picture. However, I've not looked to see if the holes are aligned. Next time I'm in the workshop I'll have a look. Also, all the ballnuts I've bought (various places including Fred) have oil holes so makes me wonder if the ones which don't fit (and don't have oil holes) have been "sourced" elsewhere and not been to the standard. Did Fred have a drawing of the ballnuts on Aliexpress? If you measure your part and it is not per the drawing it is worth saying so. Good luck with it - I've not had to return anything to him so I don't know how good his returns policy is . . .

    I contacted him, now waiting for reply. We didnt have any drawings it was only been said that ballnuts are comming together with ballscrews. But yes they are diffrent the flat side of the "good" ballnut goes flush with housing or lets say are in thevsame plane, whereas others has a step between them. Hopefully he will be able to send me the balnuts and i will just swap them.

    Fred is decent, i have had a couple of bits missing and one BK block was sent as a BF instead - in all cases he fixed the error, the only issue was the time delay due to distances.

    Put some pics up showing exactly what is wrong ie. is it the ball nut or the ball nut mounting that is wrong. I doubt he will just send a ball nut without the screw
