I have my BF20L already converted to CNC but without disassemble I can't be sure if a 1605 double ball nut on the Y axis will fit or not. To be more precise will the nut hit to the base when traveling to both directions?

I believe G0704 owners can also answer my question.

I've got a PM25 clone if that's similar sizing.
Fitted double nut to that fairly well.
Had to remove nut to reverse it so the bolt end went to the back of the Y with motor end at the front.
If you can, fit Angular Contact bearings too.

Do you not have the technical abilities to disassemble that axis and see for yourself if a double-nut will fit and allow full range of motion?

Stuart,

It's not about ability. It's about saving time and effort. But here's your answer:

To disassemble the table I first need to disassemble the enclosure. To disassemble the enclosure all the individual oil lines must be removed because these lines and the Z axis cables comes trough holes on the enclosure. Once these are removed I need to lift the whole machine and put somewhere because it is impossible to remove the Y axis because the chips tray has a high profile front and rear walls so I can't simply slide the axis and remove.

You see figuring if I can use a double ball nut on the Y axis is quite a work and will take some time. Instead all this trouble someone with BF20L or a similar machine can easily answer just by writing "Yes" or "No" and that is all I need.


Next time if you have the answer I need please let me know. Otherwise please don't ask helpless questions.

After that, I wouldn't tell you even if I knew... WOW!

Suat,

I was not trying to be 'snarky' in my response to your question. The pictures I found of a BF20L show no enclosure, so I had no idea following my suggestion would be so difficult for you. If the construction of a BF20L is anything like that of a G0704, then a double ball nut will fit..with minor modifications.

If you look at my build of a G0704, you'll see pictures of the 'Y' axis casting with ball nuts installed...they should be in the first 15 posts somewhere.
