Big CNC Brief Guidance

Hi @CNCtechs & @BigCNCers

Greetings! I am in the process of creating large signage. I have designed my vector and will like to give it a go (attached). I have been induced onto the large cnc.

I was wondering if any big CNCers are around tomorrow/ some point in the near future to very briefly point me in the right direction?

Thank you!

I’m in on Friday if that helps. Not done anything like that and not sure if I’d be of any help. What are you unsure about? Might be best to get help from a CNCtech.

I think you should be fine using v carve and what is shown in the induction. Maybe rewatch the video re multi tool use for carving text because that’s relevant here.

I’m guessing it is a sizeable sheet eg. 40x60cm?

However large though I’m seeing the font you’re using sports tight ligatures so you might need a very small bit and a big one for the pockets. Consider using actual 3 tools for the pocket and experiment how long variations might take.

Lastly we have a simplified clamping system but it requires you to watch out that you don’t hit them. If in doubt just trace the nearest g code.

Thank you very much @dannz and @Christian

I attempted to practice after the induction and, for some strange reason, I could not recall how to launch the cnc program after creating the G-code in VCarve.

Thank you for the pointers @Christian I am in today and will give it a go!

Turn on the Linux PC (the Dell mini desktop under the counter). Switch to it using the KVM (quick double press on the keyboard key with white sticker). Debian will boot up. On the desktop is penguin icon with shortcut to CNC. Doulble click to launch that. Username and password is ‘cnc’. Post here if you need any more assistance…

Thank you! :smiley:

Hi @dannz @Christian

When I double click the white button it switches but I get a no signal message on the monitor.

The Linux’s PC appears to be on? (Pictures attached)

Thank you


If the PC is on, then that looks like a problem. I’d suggest seeing if Ni is in Arch 1 and if so, ask him to look at it. Failing that, check the connection at the back.

I’ve left the space but I will like to flag this issue with the @CNCtechs just incase it needs to be investigated. Thank you :slight_smile:

Thanks for doing that. I’ll take a look also when I come in tomorrow.

Recently the linux pc has started that issue. If you switch off the PCs top switch and then back on ( the laptop will remain on because of the battery so you won’t loose your work) the issue is solved. It’s a temporary solution and we will find the source of the problem and fixed it

Please do not unplug/recable the linux machine to make tests until one of the techs is around

Thank you. Yes everything is still attached. I just turned off the normal on/off switches at the mains.

Not my intention. Just going to see if the PC is booting up.

Linux PC seems to start ok. Definitely no signal via KVM.

It works ok if you switch the kvm to the Linux PC before booting up the Linux PC. The easiest way (suggested by Federico) is to turn off the mains switch for PCs, then kvm, then turn the mains to the PC back on. The windows pc is a laptop that will run on battery when switched off briefly. After that, you should be able to switch using the kvm as you’d expect. Not great, but it works.

Thank you @dannz I Will be in this week to try again :blush:

@CNCtechs: I am at the space now and I can’t get a signal of the Linux pc on the screen. I have the windows laptop on the screen .
As per advice above I switched kvm to linux and then rebooted / switched the Linux machine back on - but no luck.
Everything seems to be plugged in correctly (I didn’t change anything).
Any tipps?

I was the last person to use it late last night. KVM to Linux was working fine. I did shut down the Linux PC. It might not automatically restart. If you’ve not already done that, check if it’s on and restart it from the power button on the PC.

You could also try turning the monitor off and on - it will search for the signal.
