ThePog Posted September 8, 2020 Author Share Posted September 8, 2020 And fuck it, let's add the Z axis. Also I spent some hours learning how to set up the vfd/spindle. This should be good to go as soon as I find some four core cable for it. 2 Quote Link to comment Share on other sites More sharing options...

Popular Post ThePog Posted September 11, 2020 Author Popular Post Share Posted September 11, 2020 A bit of a win today. I have been looking for bits of MDF at least 3m x 1.4m so I can have a bed with no joins in it, this was proving difficult and/or stupidly expensive. Then I remembered a place next to where I got some electroplating done that had stacks of random MDF sheets lying around. I rocked up yesterday and told the the man what I was doing and what I wanted, he was super interested and said he would sort it out. I got a call today saying the sheet was ready, so I swung by to pick it up. He had cut 2 sheets of 18mm to the exact dimensions I wanted and sold them to me for only $50, what a GC. I just slammed one on now, looks sweet. I have also been setting up some cable routing and the prox switches, just the Z axis to go; 10 Quote Link to comment Share on other sites More sharing options...
Ned Posted September 11, 2020 Share Posted September 11, 2020 Fuck yeah! Nice! I found some sheets of 3660x1830 or something like that. Ended up with a torsion box table 3500x1750x200. Pretty bloody heavy haha! But for $50, thats a fucking win! Bet he'll want stuff CNCed every week for $50 now 1 Quote Link to comment Share on other sites More sharing options...

ThePog Posted September 13, 2020 Author Share Posted September 13, 2020 Fuck I'm cranking this shit out. I set up all the prox switches and spent yesterday crashing things into them while trying to get my head around the LinuxCNC .ini file that controls all that stuff. Pretty much got it sorted but I really need to understand how the soft limits work a bit better. Then I sat down and dicked with HSMXpress which is a cam add in for Solidworks that seems to mostly do what I need it too. Shit it's a steep learning curve, I needed a few revisions of the setup to get the router to do anything sensible. I need to spend a lot more time learning about G code as well. However I did get a basic functional setup working, and here it is; Fucked with the spindle but I can't get it to go, probably a setup thing in the LinuxCNC .hal file which I also need to spend a lot of time learning about. 4 Quote Link to comment Share on other sites More sharing options...

Speedy fast progress! Just run the spindle manually? Had similar problems setting up mates router that was our fix until figuring out the configuration/communication. 1 Quote Link to comment Share on other sites More sharing options...

Theoretically it is straightforward but I am a nooooooooob. Quote Link to comment Share on other sites More sharing options...
ThePog Posted September 17, 2020 Author Share Posted September 17, 2020 I finally got the spindle running, as expected it was me being a dumbass about the VFD setup parameters. Although for some reason it is only getting speed control from the potentiometer on the VFD. I am ok with this though as it will allow me to experiment with speeds and feeds. I also trammed the spindle to cut straight and flat, good enough to be able to face the table anyways. I also did a hard out calibration of the X and Y axis so it would cut accurately. I also made up a longer control cable for the big servo, that was stressful. This means everything is nicely tucked away in the cable trays now. Next is to buy a cutter and face that table... Then I'll design a vac table and make it. After that it's all cash money. 8 Quote Link to comment Share on other sites More sharing options...

ThePog Posted September 21, 2020 Author Share Posted September 21, 2020 Man I am fizzing over this thing. I surfaced the table over the weekend so I had a decent base to work with. There was some dumbfuckery with the length of the cut surface as it was 40mm or so too short. It turned out my calibration was just wrong, what a dick. After I sorted that I then I realised that the odd misalignment at one of the corners of the bed was not a poorly cut bit of laminex, it was the belts moving at different rates due to different stretch. I sorted that tonight and then started cutting the vac table. I'm breaking it out into small operations so I can learn some shit about feeds. This is the vac inlet pockets; Come up good, those screw holes were routed too... I also set up spindle cooling as I didn't want to toast it, I bought some tube from mitre 10 and went redneck on it; This will get tidied up and made to run automatically a bit later. 9 Quote Link to comment Share on other sites More sharing options...
ThePog Posted September 23, 2020 Author Share Posted September 23, 2020 Made a dust shroud tonight; Might need some longer brushy stuff but that was what Mitre 10 had last Saturday. We'll see how it goes. Also I hand modified some g code to adjust the speeds after checking the vac slot program, I am a software engineer as well now bitches. 5 Quote Link to comment Share on other sites More sharing options...
ThePog Posted September 24, 2020 Author Share Posted September 24, 2020 More vac table action. I had to drop the spindle a bit so it was working within its limits which is why the dust shroud is so high. Also some dust extraction happened. I imagine this is all pretty tedious for everyone, but I am loving it. 4 Quote Link to comment Share on other sites More sharing options...
NickJ Posted September 24, 2020 Share Posted September 24, 2020 Tedious yes, but totally understand how mesmerising it is in person when you get a computer to do something useful! We found the hood visually got in the way when working on 3d stuff, eventually replacing the brushes with clear vinyl, even then you'd be pulling the suction hose off and manually cleaning up to check on cut quality etc. Keep throwing up the updates, keen to see what you'll get it carving! 1 Quote Link to comment Share on other sites More sharing options...
Stu Posted September 25, 2020 Share Posted September 25, 2020 Out of interest where did you get the brushes for your dust shroud? I need to make up a new shroud for one of my machines. Quote Link to comment Share on other sites More sharing options...

Popular Post ThePog Posted October 3, 2020 Author Popular Post Share Posted October 3, 2020 So much fucking around sorting that vac table, mostly due to my stupidity. But it seems to work as long as the stock lying on it is flat and has a decent finish. Spot the extra feature pocket that somehow exits onto the steel framing and had to be recut in a different position. I read the home security thread looking for good IP cams so I could set it running and keep an eye on things while still working at my computer. I happened to see someone's comment about using old cellphones as a cam. That shit sounded right up my street and it happened straight away. Perfect. I also figured out that you could jog things specific distances in LinuxCNC, this helped immeasurably with getting the tool heights right. I don't have a touch off plate, but I do have a multimeter and some aluminium tape, so that's how it happens for now. And purely for @flyingbricks viewing pleasure; Never say I don't follow through on my promises.... 15 1 6 Quote Link to comment Share on other sites More sharing options...
