--- Quote from: merc on December 26, 2017, 07:50:59 AM --- DDCSV adds circle instead of the arc in the bottom left corner. Any ideas how to fix this flaw? --- End quote --- I have had same problem, when value of pulse/mm was under 250. (for X and Y axis) I've increased it to 500 pulse/mm, and now controller works well. I use linuxcnc or emc2 postprocessor for G-codes. |

I know that setting no's. 33 (motor start speed) and 416 (time between DIR and pulse) can have quite an effect when pulse settings are outside the normal range. My Z axis was the issue because I had it set to 12000 steps/in (yes, I use inches). It was so high because of using a Gecko G540 that has 10x dedicated microstepping that can't be changed. I set my #33 to 20, and #416 to 200. I don't fully understand these settings, but thanks to member PPRINT (Rob) for pointing this out to me back around post# 635. |

Did you double a pulley size or gear ratio or something? --- End quote --- No, I use not gear ratio, stepper motor drives directly threaded spindle by a clutch. Motor moves 1.8 degree/step, so the step/rev=200 Pitch of threaded spindle is 6.35 mm. This way, 200 step moves to 6.35 mm, therefore 31.496 step moves one mm. (31.496 pulse/mm ) Now, need to use microsteps, stepper driver knows it. If the setup: -half step 31.496 x 2 = 62.992 pulse/mm -1/4 step 31.496 x 4 = 125.984 pulse/mm -1/16 step 31.496 x 16 = 503.937 pulse/mm (I use it ) 503.937 pulse/mm x 25,4 = 12800 pulse/inch |

Good afternoon! I have been in touch with the original engineer some more and we've got a late christmas present for you. The update we have been working on is going to be huge and will allow adding custom cycles through plugins in the future, allow more langauges than just English and Chinese, will fix bugs and add more functionality. This update is the first one during this series of updates. It includes our community translations as the new default English translation. This attached firmware is likely not stable and may not work properly, but testing is very welcome. I have not been able to test it, since I am not at home, but instead with the family during the holiday season. You can always roll back to a stable version using PandoraInstaller for installing either the factory version or the modded firmware. I have attached an update archive to this post. You will need to unzip the contents to the root (uppermost) folder of a FAT32 formatted USB stick and follow the usual instructions. Best regards and happy holidays, Benedikt |

Merry Christmas Benedikt. Wow can't wait to see the new release. I hope the new manual will list all the G and M codes (and any other) that are supported in this release. Also a list of what has been fixed (like a release note) As you know i'm into backlash!! Again many many thanks for all the hard work you and your colleagues have put into this controller. Will, Dublin.ie |
