    One problem might be that may run into problems or project needs that I can not take care of with the limited tools and materials to take with me. But let's see. If I get stuck so...

    Re: Small Portable Machine

    That can be done...Many Full Time RV folks have their roofs plastered with solar cells, serious batteries and with a 2-3 kW inverter you could easily run a cnc machine, at least with such a small...

    Re: Small Portable Machine

    So...I did buy the Chinese 3040 4-axis machine but with with a real spindle and paid (IMO ridiculous) $816 with the knowledge of improvement needs. Took a bit of a risk believing the sellers...
  6. Re: Chinese 3040 parallel port machine and MK3/4

    Thanks, I am sure I can make it work somehow.
    The MK3DRV looks interesting. Is that a Trinamic Silent Step chip on there or what is the actual driver?
    Also, while the nominal voltage is supposed to...
  7. Chinese 3040 parallel port machine and MK3/4

    Can I expect the 26/25 pin connector of the MK3/4 board hook up with the DB25 of a cheap Chinese 30/40 (like this one) machine and work somewhat out of the box?
    These are intended for PC parallel...

    Re: Small Portable Machine

    Thanks for the ideas but both X-Carve and Shapeoko are too big to fit the 37"x22"x22" compartment

    I am doing some research and right now I am leaning towards getting a Chinese 3040 machine and...

    Re: TNG Progress

    I have not tried it with TNG. But all my software has very generic g-code output that can be read by 90% of all machine controllers. There are some exotic European machines that made trouble and I...

    Well, may not have been perfect but worked well for me to see how the machine would move and even give a rough idea how the machined part would look like.

    Since I am at it....the ability to...

    Re: TNG Progress

    Nice!.

    Now, does this new version also display rotary axis jobs (x-z-a or y-z-a) properly as 3d projection (like the old USB-CNC software)? This is holding me back from switching to TNG.
  13. Re: jerky execution of the control program.

    I am using the MK3/4 with the old USBCNC soft/firmware (not TNG). But I have experience similar jerkiness, slowness and sometimes lost steps when activating the path blend option. It may have to do...

    Polygonized G2/G3 Arcs

    Since I switched to the MK3 (with old CNC-USB software) I noticed that circles and arcs cut with G2 and G3 commands come out visibly as polygons. It is not much and can be sanded away but this is not...
  15. Re: Cncusb fusion 360 4axis post processor problems.

    They did ask the question about the counterfeit controller in your other thread about software limits but you did not answer on this forum.
    So did you buy your MK1 (long obsolete) from Planet-CNC...

    Re: Software limit

    Not sure why greyed out. On my machine with MK2 and another one with MK3/4 the soft limit controls are active, even when the machine is not connected. Maybe Planet CNC has an explanation for that.

    Re: Software limit

    Go to "Axes" in settings, specify the desired limits in "Limits" and activate the soft limits under "Soft Limits".
    It is kind of self explanatory.
  18. Re: Thinking about switching to Planet CNC

    For Vectric software as well as Deskproto I use the most generic g-code postsprocessors, e.g. for Aspire the gcodearcs-mm. But many others will work as well. Planet-CNC is not that picky about it....

    I found how to set the transformation in the menu. But that was deactivated and cleared after I closed the program and started again. Is...

    Re: Lookahead for TNG

    Well, that is exactly the problem. I am lost. Part of the problem is maybe my limited understanding of G-code.

    1. As for transformations, I suspect that would use the G10 L3 code? Where do I find...

    Re: Lookahead for TNG

    in the meantime I did fire it up and went back to old software as well, mainly because I know what to do. I will try the TNG version maybe with the next update. Another thing that I am...

    My latest project using the BigBamboo machine is a traditional bowsaw:
    For most of my curved cuts I do use a band saw but sometimes such a bowsaw can come handy.
