Did a bit more programming and wiring for the spindle VFD today - even got it moving although I still think there's a few setting to tweak. I also managed to enable a feature to toggle between two different speed setting inputs - one from the controller and second via the potentiometer. As well as wiring one terminal block from the hard stop button to the VFD which performs an increased deceleration. Standard spindle stopping time is 9 seconds while the estop is 4 seconds and I think I could reduce it further. I had to change from the momentary button to a latching type for this to work. Now I can call it an e-stop, and it triggers specific emergency behaviours in the controller, laser adaptor as well as the VFD. I also uncoiled the earth from the ferrite core on the spindle wiring and connected a draining wire to the cables armour. I should really have the earth as a separate cable after reading the manual, but I'm going to see how it behaves as it for now. Things I couldn't document with photos included updating the Duets config file to turn a couple fans on after the internal temperature of the enclosure goes above a certain point, which means the controller runs quieter. #VDF #VariableFrequencyDrive #Spindle #Duet #Duet2 #DuetWifi #CNC #DIYcnc #CNCcontroller #Electronics #DesktopCNC

Train driver decided not to turn the lights on during the commute, so as we penetrated the tunnel we were sunken into darkness with only a few mobile phone screens dimly illuminating the carriage. For moment I wondered if I was still going to work, or if I had been somehow transported onto the ferry to the underworld, or if my dad had become a train driver. #Work #Commute #London #Economy #Hades #Underworld

I started the next stage of the CNC controller today - wiring up and programming the variable frequency drive. Looping the spindle wires around the ferrite cores helps reduce interface getting back to other components in the controller. It also looks like a weird Christmas decoration, or a homemade bludgeon, and judging by the queue outside the pub on the way home I think people are carrying on where lockdown started. Lol. The VFD which is from @rs_components is very different from the NfLixin one is used previously. I'm still getting my head around the functionality and had it splutter the spindle around, but not properly rotate. Will play around with it again on the weekend. #CNCcontroller #DIYcnc #Spindle #CNCrouter #VFD #VariableFrequencyDrive #FerriteCore #Wires #Duet #CNCcontroller #Making #Workshop

Went into the studio today to actually work on stuff. Seems about time considering I was back at my day job (education) about five weeks ago. Spent a few hours sorting out some lighting above the CNC machine and trying to workout where I had left off. I may have lost some footage from last year, but should be able to save the next video - which will be a filler episode where some electronics go on holiday to a spacious enclosure with a large window. I started but did not finish transfering the system changes I made but didn't document, from the test rig back at the flat onto the studio controller. The worst bit is trying to remember what I was thinking or not thinking during that process. There's still a lot to do, including programme the new VFD, and also changing the intake and exit air fans to variable power pins, as they are way too loud. Also my stamina to commute is low. I'd much rather be drinking tea infront of the telly, lol. #CNC #DIYcnc #CNCcontroller #Workshop #Studio #Making #PanelDue #PanelDue7i #Duet #Duet2 #DuetWifi #CNCrouter

Just uploaded a new video where I make a 3D printed adjustable drill guide. It was quite nice to think about and make. The link to the video is available via the bio or on my main channel. A PDF manual and the 3D files are available via my websites shop. #DrillSplits #120DegreeSplits #3Dprinting #Drilling #Guide #Tools #Making #SpreadTheWord #Workshop #DrillGuid #DrillJig #PLA #PLApro #DrillChuck #LinearRails #PolymerBearings#3DprintedTools #3Dprotoype #3

Some details from assembling the 3D printed drill guide this evening - working on my kitchen table. Have to admit I'm loving the cheese yellow. The tool is surprisingly sturdy, and the chuck feels very true. But my dial gauge is at the studio, so I can't check it yet - visually it looks good. I don't think the video will be ready till next weekend. #3Dprinted #3Dprinting #Design #Prototype #DrillGuide #Chuck #DepthStop #Drill #Workshop #HandTools #Weekend #Making #LinearRails #DIY #Tools #HandMade #DrillPlay #3Dmodel #HandDrill #DrillPress #PillarDrill
