  1. Lubrication for a ball screw CNC machine

    One of my CNC machines was supplied with a syringe full of quite thick grease, which I feel is not really penetrating into the bearings well.

    I read that 3 in 1 PTFE was a good lubricant for the...

    Clicking on Y axis

    Noticed the Y axis is clicking/ticking on my backup CNC machine.

    Odd thing is, it only does it going left. Its been well lubricated.

    Any ideas?

    Re: Acrylic and metal Adhesive?

    Thanks for reply.

    No, they have to drop on. They are not proper rivets. Just screws that have a rivet like head.

    Re: V Carve Pro unwanted ramps on slots

    I have MACH3 running on laptop, I'm not sure what the controller box is called. Everything else is running fine. It cuts voids, shapes spot on. But on a one way a - b slot, it ramps as it leaves the...

    Re: V Carve Pro unwanted ramps on slots

    I'm not sure. From the 3D preview it looks like its cutting normal. There doesn't seem to be an option in v-carve tool path options for anything which would cause it as its all greyed out as the slot...

    Re: Ideal bit for M D F/Veneer?

    Thanks for your answers ger21.

    Does that apply to holes too? it only plunges to start the cut and a few holes here and there.

    Re: Ideal bit for M D F/Veneer?

    Oh ok. I don't think my spindle is powerful enough for one pass in 10mm. I'm doing 3mm passes with 2 fluted uppercut. I saw a vid on youtube where they compared bits and a straight flute seemed the...

    Ideal bit for M D F/Veneer?

    Seen lots of debates about which is the best bit for mdf.

    I find 2 flute 6mm upper cut reliable, but leaves a fuzzy edge at the top edge. (And I hear Down cut does same to bottom edge).

    Is a...

    Re: What is wrong with my CNC machine?

    Thought i'd update the thread,

    Re: What is wrong with my CNC machine?

    It went off course and I hit emergency stop. I then manually raised the Z Axis, then pressed continue in MACH 3 and it seemed to go back to its proper course.
