Sneak Peeks of Future Projects / Random Stuff: www.instagram.com/savvas_papasavva

Reached 100k subscribers recently on the main channel, and then I opened my mouth and sacred the 0.1% away. #YouTube #MiscPro #ForTheMany #Gammonxit

Been sorting out random stuff in the studio today alongside some overdue editing and list writing. I was trying to familiarise myself with what I've got so I don't end up buying multiples, and then work out what I can get rid off to make more space. It seems I've accumulated quite the collection of stepper motors, and wires, and proximity sensors. After shuffling stuff around I decided to put my GRBL controller away (on a shelf) so I can use the desk space to film the accompanying stages for the CNC manual - or any other build for that matter. #StepperMotor #CNC #DesktopCNC #DIYcnc #Nema23 #Nema17 #Wires #CNCrouter #Studio #Workshop

Was working on the larger machine today, and managed to ram the X axis into the proximity sensor. Think I pressed the wrong macro before homing, alongside having un-disabled movement before homing and not having hard stop enabled - which only gets enabled after homing. I made sure to copy that bit of code into the config.g file. The stepper end plate cracked, and the sensor popped out. Luckily I had a spare plate and somehow the cockroache of a sensors still worked. Anyway what I wanted to do was investigated the Duets issues with pausing and resuming a frequency drive spindle, which I managed to fool into working although something's wrong with the underlying code that I don't know how to access. I spent the rest of the day tidying up and filming a summary video of the new Ooznest web interface. #NeedToMakeMoreVideos #ArtMachine #DIYcnc #CNCrouter #DesktopCNC #Workshop #Studio #Duet #Duet2 #DuetWifi #Reprap #HobbyCNC #Valchromat

Re-wired the steppers with four pin ATX quick release cables yesterday, and it took me ages. Just kept making mistakes.The worst bit was right at the end everything was moving apart from the X axis, I remover some heat shrink to check the wires, and realising I'd just forgot to tighten the motor coupler to the stepper. Wasn't going to remove the connector to refit the heat shrink so I just used electrical tape to cover that bit. #Lazy #DontCNCwhenYouAreTired. #TheRouternator #ComeWithMeIfYouWantToCNC #Workshop #Wires #Soldering #ATXCable #StepperMotorHead#HandModel

Another one from the weekend, where I started to replace the smaller machine with the one I'm building alongside writing the manual. The controller for this one uses GRBL, which has a new firmware version that auto square the gantry. Unfortunately most GRBL board clone the Y axis signals, and as the steppers drivers are mounted to the controller I won't be able to bypass this and use the feature. I do have a spare Phoenix CNC controller which uses external drivers, but the new setup means you'll loose the spindle direction and coolant pins - which are reassigned to the second Y stepper. Problem is I need the spindle direction to turn the VFD on and off. Oh well. #Duet #GRBL #CNC #DIYcnc #DesktopCNC #Workshop #CNCcontroller #Reprap #OldBoiler

Finally got the spindle to work properly on the larger machine with the Duet 2 WiFi. I'm still using the old RRF2 so it partly involved writing a new post processor for Vectrics. I had to start by disabling extruder heater 0 and using the M42 command to switch the pin manually at the same time as sending the M3 S# (#=some random spindle RPM) command. I couldn't go directly to a relay from the Duet because the pin was being pulled up so I used a PWM to analogue converter as a go between. It feels like a long way of doing it but it worked. Only problem now is the pause and resume don't work as expected as after recommencing from a pause, the spindle doesn't recieve a RPM speed until the next segment in the code - effectively causing the bit to crash into the material. There seems to be a fix but I'm not sure if I have to upgrade to the new RRF3 and I won't have time to try until the weekend when I'm next in. #DIYcnc #CNCrouter #DuetWifi #RelayModule #PWM #Gcode #Workshop #Wires #Electrics #Vectric
