Hi Guys, first time poster showing off my progress.

Finally found some time to work on the C-beam build again. It appears ready to cut some aluminum, I think. Did an acrylic cut and came out really nice.

I did some quick test a few weeks ago and has since tweaked the machine and runs pretty smooth now.

I placed the controller and 24V PS on a plank at the rear. It will have an acrylic cover eventually with just a hole for the IEC cable and everything covered. I did a quick design and 3D printed the E-stop and IEC housing.

I will try to cut something aluminum by tomorrow, some brackets maybe for a 3D printer Im building.

 

Looking good! looking forward to seeing it cut!

 

Thanks Mark i'll give that a try and see what happens !

 

I'll try that again as well and hit yes this time, i currently have the machine in my living room and want to keep from disturbing my neighbor so i'll need to wait until tomorrow before testing further! I'll keep you guys up to date with progress, thanks for helping me here

 

Sounds like a good excuse to install an E-Stop

 

we do extensive testing with automotive ECUs, board warpage is obviously the worst contender. but solder joints can weaken with excessive vibration,bond wires in some IC's are also at risk with vibration.. part of the problem is that the device will go out of spec, or lifetime will shorten not just die out right. so a lot of time people don't attribute the eventual failure or see the out of spec. i see a lot of eia2/ x7r's in use and they show microphonic properties and induce noise into the circuit. electrolytics as well.

but its one of those things where talking about it (especially on the net) is a bigger deal than it is happening, its a low enough risk but its easy to avoid, i know most people don't worry about it and the fixed are plenty. i find that the swarf gets everywhere.

cheers

 

Yes i'm thinking that myself!

 

Things starting to try my patience

I'm getting errors ....

 

I have been sending the the .tap files from 1 computer as attachments through email to the laptop beside the cnc machine, would that cause me problems?

 

Beware the rabbit hole Alice - or in this case the quality/reliability hole.
Connections (of whatever type) that fail under (non destructive) test conditions fail for a reason.
Typically process quality, but all too often unsuitability to purpose - assuming the test to be suitable.
In THIS context it is hardly likely that IC lead bonds will fail as a consequence of the use that most of us will put this machine to.
Solder ? Biggest problem is with solder bath times being inadequate for the LARGE power connections to get adequate flow, i.e. they fail because they came out of the bath BAD.
By all means keep the control board away from the machine if you WANT to, but it won't be because there is a NEED to.
There is usually a good case for keeping all leads no longer than necessary.

 

what cad/cam program are you using ?

try one of my test .cnc files

 

Hi m8, i'm using aspire v4 with grbl panel, i have downloaded your file and i'll see how that works, i used the g code pencil drawing file and that worked perfect, i think aspire 4 hasn't or doesn't support grbl, i have been looking at threads for the shapeoko and see that they had do put files into the post processor in vetric or aspire for there's to work?

 

I have outputted .nc files from fusion 360 due to some g codes, grbl doesn't like it neither does openscan, no issues with outputs from sketchucam

I remember reading somewhere that there are known issues with grbl panel and the xpro

 

I'd really like to get this working to do some test cuts, the misses has been playing with aspire and said its really easy to use so if i get stuck she can tell me what to do. I just need to get both programs coordinating in harmony together.

 

yeah luckily moving a circuit board and power supply a short distance is a very very small rabbit hole. an ounce of prevention, and all that..

 

Grbl doesn't support the M6 command. I ran into this issue in the past. You should take out that first line and see what happens.

I think i sorted it early hours this morning, i downloaded a trial version of the latest aspire and copied 2 grbl files then put those 2 files into my post processor folder in my version and as far as i can tell its working!

 

I turned some nylon and drilled a hole in it for a pencil to try drawing something, i have left the pencil 'just tight' so if i get the depth wrong i wont cause any damage

 

Going to try and get a refund from robocutters, i have heard nothing at all from them since i placed the order and i can't get a hold of them at all, no answer to lots of emails and his mobile phone is switched off every time i call him, i also text him a few times without reply, very poor service....buyer beware, i'll not be dealing with them again! They have had plenty of opportunity to contact me and i have heard nothing, didn't even get a confirmation email or invoice and still no goods arrived.

 

I tried drawing with the c beam, here is the result, there is 2 videos just look at my other videos and you will see the others

 

Thanks Joe, i think lol, seriously though it is a bit noisy

Might have to bolt it down or stick rubber feet on it. everything is tight.

 

Congrats Slugster! Aren't those first days trying to get a machine up and running fun? And, thank God when everything finally starts running right!

I agree that it seems noisy, but if it's just loose on the table, you will hear each step from the steppers. Screwing a few corner blocks into a 3/4 piece of plywood will do a couple things for you - First it will help to keep everything square and running smooth. Secondly, it will add mass, which helps with noise and vibration. I'd also suggest adding 4 rubber feet to the bottom of that to even help more.

Have Fun!

 

Thanks! Yes I'm thinking along similar lines, my first thoughts were to pour melted lead down the holes of all the aluminium lengths but the misses said that's a stupid idea lol. I'm just sorting the electrics out a bit but my dog 'diesel' is needing his walk, that's him to the left of your screen with the bone, he is nearly 5 now and if he wants something he soon lets me know!
