Machine: RAMPS/Arduino from Moshi
Board: New C3D
Firmware: Smoothie - as per C3D Firmware
Crashing / Gobbledigook on LCD
First, let me say that the C3D upgrade from Ramps (I’ll do a build dairy later) was lovely - scary, but so nice when I got my head around it!
Now, at the moment I’m having an issue with the LCD - it’s come up ‘right’ twice, but the rest of the time it shows the mumbo jumbo as per the picture. I’ve taken out and replace the ribbon and the GLC adapter multiple times - I’ve even ‘removed the cartridge and blown on it’ ;-). Nope, still gubbins.
The other issue, and I don’t know if its a LB or C3D issue, is that I get ‘crashing’. Par example:
I’ll be setting a line up for a ramp test. It homes when I ask it to run - notice it doesn’t run. Then it says that it’s busy, and does nothing. Sometimes even when I power on off the C3D card and close/reopen LB. I’ve moved it from X/Y end stops it case that was it, but no. Restart Mac and hope. Leave card unplugged and hope.
The other thing is that is will frequently get to the origin on the job, then just stop dead. It’ll fire the laser at where it wants to start, then just shut down. If I run it again there’s a 50/50 chance of the job being done, but in the meantime it’s forgotten it’s position, and will crash in to the gantry end. If I remove a load of cut layers and go down to a bare minimum then it will sometimes start.
In short, I’m a td perplexed and hope that someone out there can assist!
FYI - running a Mac! , most up to date version of LB, have made DOUBLE sure that the most up to date firmware is installed by reinstalling ‘just in case’!!
If I unplug the board (power), then plug back in enough times I can get the LCD to load, but then in a minute or so it reboots itself automatically.
I have taken out x & y, and laser modules, leaving a ‘blank’ board other than USB and LCD. Still happens. This may sound stupid, but when I ‘pull’ the board from its rightful place and put it on a flat surface it works better for longer…
Minor Update 2
There seems to be something specifically wrong around the comms. I run a Mac with Parallels for Windows use. I decided to flash the firmware with Windows ‘just in case’. That was fine. However when I connected the board to the computer I got multiple flashes of ‘do you want to connect to you Windows 10 or Mac?’ windows. I’d select, it would come up again, which indicates that the board is dropping the connection to the computer and reestablishing it, dropping, reestablish etc. I’m using a brand new C3D USB cable, and I’ve also used a cable from my printer, which worked on the RAMPS setup previously, and the same thing happens.
Minor Update 3 - last one for tonight (UK!)
I diidn’t know it, but the Laserboard can power the steppers wiithout the K40 being turned on. And as it happens, the crashes take longer to occur. It still can’t ‘do’ anything, and it crashes as soon as you point it in the direction of ‘lasering’ something, even if the laser ‘maschine’ is off, and comms go down, but perhaps some breadcrumbs? I imagine that when the machine is on it causes some conflict between what it thinks it wants to do, and what I’m asking it to do, hence the longer time between crashes as when the ‘machine’ is on I’m clicking buttons, sending to home etc.
