    Hello.

    Perhaps it's too late for an answer but I'll make a comment any way in case it can be useful to anyone having about the same idea. In fact many new frame quilters are built upon this idea...

    Hello.

    You need to confirm on the precision of the supplied screws. It's common to be supplied with C7 screws which work fine for me as I work with fabrics.

    You must also ensure that a minimum...

    Re: Question about GRBL Arduino CNC systems.

    Thanks for your comments.

    Based on experiences from friends attempting to use, let me call them standard CNC controllers, to process fabrics, the final results are not good enough.

    As I...

    Re: Question about GRBL Arduino CNC systems.

    Thanks for all your comments.

    To further give you an idea of what I want to do is to control a chain quilter as the one depicted to produce the patterns shown on the other pictures.

    Question about GRBL Arduino CNC systems.

    Hello everyone.

    I´ve been asked if there is any standalone GRBL Arduino system.

    As far as I know it always requires a PC to upload the pattern program to be executed and that it is specially...
  6. Re: MOSFET replacements for DM860H stepper drivers.

    I apologize for not replying sooner but I was required to do some fieldwork.

    I thank you for your interest. I finally found the parts and the drive is up and running. Fortunately the damage was...

    Re: SVG to G-code converter

    Hello.

    The posted files are the ones I´ll be using to test your software. This is the type of patterns that our new machine will be required to quilt.

    I´m in the process to convert these files...

    For an unknown reason I could not reply with a PM.

    What I will be doing is using some of my already converted files so that it will be possible to compare the generated G codes. Then I...

    Hello.

    Unfortunately localhost is unable to open.

    It would be interesting to try your program.

    Hello.

    I know nothing about those two programs. Yet if they can exchange their native formats with DXF it may be possible to do a double conversion, say GIBBS to DXF to MASTER and viceversa.

  11. Re: New to the Forum, Looking for some help with my 3018 CNC

    Hello.

    First of all I´d suggest you check your power supply. It appears as if for every movement the voltage diminishes and the motors need to wait until power is fully restored.

    Hello.

    In case you haven´t seen the other post here is what I have found so far.

    First I have to warn you about some apparent distortion in the Y axis of the posted pictures as the screen...

    Re: Help, Please.. X axis shift after each pass

    Hello.

    To ZASto. While there may not be couplings the pulley is still screw locked to the motor. Hence, there can be slippage.

    You can check the other post by CNCwoodMAN where he shows his...
  14. Re: Circle pocket, via adaptive clearing, cutting off center

    Hello.

    The fact that your machine does not home correctly at the end of the cycle even when cutting air tells me there is some sort of configuration problem. That is also reinforced by always...

    Re: Help, Please.. X axis shift after each pass

    Hello.

    I suggest about the same. Check your couplings for slippage.

    If possible try running the same program but replace the tool bit with a pen. Make sure the router does not spin. The idea...

    You have to check your VFD manual so that you get the codes to access the parameter table and to check on what parameters and in what ranges you can set them for your particular...
  18. Re: Y Slaved motor keeps turning when Y axis is homed

    Hello.

    As a simple test I suggest you manually press the slave Y motor Y+ sensor as it reaches home instead of the emergency stop.

    It may even be easier to interchange both sensors by switching...

    Re: Help, Please.. X axis shift after each pass

    Hello.

    I suggest you check the couplings both at the motor side and at the transmission side.

    Remember that even though they may appear correct under stress they can slip.

    Re: Temperature to affect springs force?

    Hello.

    Given your new conditions it seems that you did anneal your springs softening them and thus reducing their strength. Hence the result of the doors not closing.

    Re: Chinese linear scale Need Pin out

    Hello.

    Without knowing that scale I´d say your wires are as follows:

    RED : +5V
    BLACK : 0V/GND
    YELLOW: Signal (A+ or B+)
    WHITE : Signal (B+ or A+)

    Are your circles perfect circles? It might be possible that the parts flex when they are machined thus distorting the geometries.
