These 3D printed mounts look great! You should share them on thingverse or something.
I haven't got the chance to finish the firmware update for the separate PID yet. My wife's mother was in the hospital the week before, and a few days ago she passed away. Hoping to get to it done on my breaks at work.
Thanks
Thanos

OK really sorry to hear about the loss
sure ill share them on thingy and post the link here,
look forward to the PID update when you have the time.
Thanks

Thanks OK I successfully implemented the P part of the PID. Now I'll have to copy the additional code parts to I and Dr. I also added a selection for single PID for all motors or individual PID for each motor for backward compatibility reasons ( Fabi's tool for example). I'll have it ready tomorrow possibly ready for beta testing, if there are volunteers. Thanks Thanos |

thanks

All coding is done. Added a few other functions from requests I had as well. I'll upload it in about an hour.
Thanks

OK great, wont have time to have a proper look until the weekend but ill probably flash to AMC tonight and have a quick look depending on time. in the mean time link to pot bracket and coupler for anyone who might find it useful in future: www.thingiverse.com/thing:1760257This is friction fit for BI technologies 6127 pot and 090 gearbox shaft |

tronicgrOk a first little update, New firmware loaded successfully and everything is working. I know you said separate PID could be tricky due to small display but you have implemented it great thanos, its easy to use. After very breif tests it seems to be helping to stabilize things but i need to test further tonight/tomorrow. Will report back tomorrow. Thanks

Seemed to be making some good progress with new firmware, had things running more stable than ever before with vfd starting current of 0.3 (down from 0.6) then problems... What is it with these cheapo 24v supplies for 6dof board?  Just had the 2nd one go bad on me. They start out with a stable output of 24v then over time they seem to start putting out more and more volts. Was having some issues and then one of my 6dof chips popped (have plenty of spares) Checked the voltage and 6dof board was receiving 35v!! Even after adjusting the pot on the PSU its still putting out more than 30v now, was a good stable 24v when new as I checked it when first installing. Have ordered ANOTHER new one. Cant seem to find any better quality alternatives, if any one has come across a better option then would be great to know. |

It seems these Chinese power supplies use low quality parts (knock offs) most of the times. I guess they veer off after they get heated as they are based on internal resistance (pot) that may vary due to temperature. A better solution would be using a power supply designed for industrial applications as this one: www.cdiweb.com/ProductDetail/RD50B-Mean-Well-USA/257959/Thanks Thanos |

Thanks for the link Thanos, I have another ebay PSU on order which will at least get me up and running again.
UK supplier but i guess they are all sourced from far east as they are all a similarly low price.
Ill look for a similar supply as the one in link and probably order one as im worried this over voltage may
cause more damage to the amc or 6dof board.
Its quite dramatic when one of the chips blow in front of you!!
was worried it had wrecked the board.

Its quite dramatic when one of the chips blow in front of you!! was worried it had wrecked the board. Its hard to damage the amc1280usb board, but the 6dof ext board is more prone due to higher voltages involved. Thus the reason I placed IC bases for all chips. I hope you find a good PSU that doesn't give any more issues. Thanks Thanos |

yep that is the same problem ! bit of a relief to know im not alone  Have printer up and running, just designing some couplers and brackets should be good to test this weekend. hopefully with some combined brain cells we can get to the bottom of this. Its my first 3d printer and im loving it already modded with different bearings and will be adding cooling and support mods at the weekend. was surprised at the print quality even out the box as it wasnt the most $$ model. Do you have this problem at that time? Some help with setting up the 1) Ki and Kp of the inverter, i should be doing this with full load on platform, but i need to be sure before setting up the platform 2) PID settings of thanos board I am sure there is relation between both this settings I cant get fabi software tuning to work so i need to tune it manually. Can someone suggest PID settings and way to tune it manually. This is Ki and Kp settings from manual  |
