--- Quote from: librarymark on March 17, 2017, 06:45:12 AM ---Folks - I am a machinist hobbyist from Michigan, USA, and have been watching this thread with great interest. The work on reverse engineering this little thing has been nothing short of amazing! :bugeye: I am building a 2'x4' cnc router and would like to try a DDSCV1 on it, but I have a question that I am hoping you can answer. It will have two steppers on the long axis. Can this unit drive them from separate outputs, or do I have to tie them together on one output? This is easy to do with linuxcnc; how is it done with the DDSCV1? And to the gentleman who wrote the Pandora configurator PHP script: Part of my day job is web interface design. May I have a copy of your scripts so that I may tinker with it? I like what you have done, but I think we can spiff up the page with some tabs and such, and maybe a guided wizard. Thanks! Mark in Dowling, MI --- End quote --- Welcome, librarymark! Thanks for the kind words, glad you liked it! :beer: I infrequently design websites for other people on request too. I was quite busy and had no time for the design. It really is a pain to use and honestly does not look too visually appealing as it is right now. I would be glad if you would give this a shot! Especially a wizard would be great. I would also need a tiny admin page, where I can trigger the scripts to re-read the original firmware files to convert them to json files. Currently this is done by passing special GET and POST parameters to the front- and backend. I will send you the code, however it is currently quite unpolished and should really be reworked. Tell me, how you prefer to handle the front-end and I will greatly improve the back-end. |

I found the firmware for RMHV2.1 (ddcsv from ratt motor), Inside this zip file are some texts translated into English. ( inside all of *.nc files ). There are really valuable comments as i.e "(Reads the current machine tool coordinate position ?ÁÈ?µ?Ç?µ??ß?úе?ø?êÎ?ÖÃ) #20=#864 #21=#865 #22=#866 ;Determines whether the system uses the fixed position tool presetting mode or the current position setting mode (?Ì???Ôµ?Ä?Ê?ÏÂ??Çó?öX??Y??ZµÄ?ø?øÁ?) IF#571EQ0GOTO1 #1=#572-#20 #2=#573-#21 #3=#574-#22 ....." Maybe can serve to understand all of variables list |

DDCSV does not allow you to configure the subordinate axis as in the Linux CNC or MACH3 --- End quote --- Yup - two motors on one axis. That's too bad. So I would have to do some sort of pairing after the controller. That would be a nice feature to add. |

I am simply tieing the signals of my axis together. |
