OctoPrint instructions

The problem I faced with OctoPrint was that when it would initially connect or when it needed to be restarted after installing a plugin, it would reset the control board which would cut power to the SSR. Then the system would have to be powered on again by pressing the start button. To solve this I ...

[MOD] Auto shutdown with & without OctoPrint

When I started on this project I wanted something that I can switch on or off on-the-fly. Sometimes I'll slice a design and send it to the printer without checking the estimated print time. When bed time comes, if it's still printing, I have to leave the printer on all night. No longer! This will wo...

Re: Automatic shutdown mods

Here's a schematic I made that's exactly how I wired it. Tomorrow, after work, I'll try and upload the files for the enclosure I made and I'll update the first post with links to parts I used, etc.

Re: Automatic shutdown mods

It works! Have to hold the button down a few seconds to power up, but it stays on whenever OctoPrint reboots and when the ramps board resets, which is what I was going for. There's about a two second delay after sending M81 until it turns off because of the capacitor but that's no big deal.

Re: Automatic shutdown mods

pF is picofarad. You can get 1 farad caps for car audio systems that go for around $70 and up, and they're about the size of beer cans.

Here's the one I'm using: http://www.mouser.com/Search/ProductDet ... KW1A223MRD

Re: Automatic shutdown mods

I have everything wired up, I just need to connect to the printer's power supply and test it. I wound up designing my own, smaller enclosure, that includes a place to hold the capacitor securely, a 30x30 fan and vents. I decided to add the capacitor because if OctoPrint restarts for any reason (inst...

Re: Stock Firmware from HICTOP

I contacted them and they sent me source code. I didn't try to compile it as there's more current source here and Roberts_Clif was kind enough to help me get it configured correctly for my 3DP-03. I don't think this is the actual source code they use, though, just what they send to people when they ...

Re: Automatic shutdown mods

For anyone following along and planning to do this, you need to define POWER_SUPPLY as 2 in Configuration.h. Conditionals_post.h illustrates why: #if (POWER_SUPPLY == 1) // 1 = ATX #define PS_ON_AWAKE LOW #define PS_ON_ASLEEP HIGH #elif (POWER_SUPPLY == 2) // 2 = X-Box 360 203W #define PS_ON_AWAKE H...

Re: Automatic shutdown mods

Right. Maybe adding a capacitor at the switch will make it so you don't have to hold the button down. I'll have to experiment.

Re: Automatic shutdown mods

It should only take a second or two. The Arduino control board boots fairly quickly.

Re: Automatic shutdown mods

I even emailed Hictop last week to inquire about getting this board to work with a relay using the PS_ON pin. Here's their response, haha 3DP-03, the mainboard can not support that parameter. Even the Marlin firmware can edit, but can not used well in 3DP-03. Sorry for that. I'm going to take a vide...
