He3D Help please.

I have scoured the different forums and have tried many different combinations of the firmware and configuration. This is a second hand delta printer that the previous owner could not figure out, but no matter what I refuse to have it beat me. I WILL figure this out, but any help would be appreciated. I started out with 2D drafting, transitioned to solidworks, and now am infatuated with the 3D printing. I have a makergear M2 as well that was printing beautifully until I got a little too big for my britches and upgraded that to a dual extruder. That one is almost back to serviceable, but I’m waiting on the nano fuse I blew when I arced my hot end. Sorry, back to my original request. Any help with the appropriate firmware and configuration would be super helpful. It’s fully assembled (except the guy before me wired the end stops to be n.o so I know I need to change to inverted. Past that, I’m a bit lost on the correct firmware and configuration to at least get this printer going. It has a heated bed and will have the self leveling feature. I do have a dual extruder for it as well but am not willing to attempt that yet until I get it up and running and gain a bit more knowledge. Thanks in advance!

I think the important first step is to figure out what kind of controller board you have? Is it based on Arduino? Can it run Marlin? Are there any identifying markings that you can Google to get going?

Hi,

If its a He3D printer it electronics should be “default” Arduino mega + Ramps 1.4 board.

Do you have an LCD for it?

Here is a Firmware for it, but i think it should have loaded by default on the arduino:

https://github.com/rruggiero/HE3D-DLT180-Kossel-delta-3d-printer-firmware

BUT!

I strongly suggest to use the latest Marlin FW for it, and use the config values from this old FW to the new Marlin configuration.

If you have no idea yet about this FW stuff an how to modify upload to the printer let me know and we can start from the basics.

For a delta the end stops are critical for the first moves so they must work before any movement made with the printer.

Use pronterface to connect to the printer and send the M119 command to get endstop status and to check if they work.

If you need more assistance I also offer skype and team viewer support so I can connect to your PC and show and get the job done. I don’t ask anything for this just willing to help you out as i am keen on delta printers.

Regards,

Tamas

i would have offered same help as first guy but I charge for my support. Anyways, make sure your using Arduino ide 1.0.1 to 1.0.4 versions. The lcd and other libraries changed in the revised versions of Arduino ide. Guy sent you firmware. Autoleveling is pretty much in there already. Configuration.h file is where you make your changes if needed. One of many tabs that is the firmware. I have a video on YouTube for uploading the firmware on a board. Really there are many showing how. Basically just set up you port to correct USB port, will pop up when USB plugged in. Set your programer to Arduino as ide, set your board to the correct board, if it has the 2560 atmel chip on it then it’s a mega and set board to mega adk. Or to the board you have. Then upload the firmware. Will compile first then upload if it compiled correctly.

You shouldn’t have bought a Delta. They don’t work.

I forgot to mention, many have issues with Windows 10, etc updates. May need to just update the drivers. Bit should make sure the blink sketch, in the examples file folder of Arduino ide. Upload that and should see an led blink on the mega. USB cable and the mega board and your PC. Three things and should check the 3.3/5 volt regulator on the mega as sometimes people can burn them out by overloading the regulator. Things like adding a Bluetooth, fan controller that uses servo outputs, large or full graphics LCD, all these add up in current not to mention the board itself and the stepper motor drivers and end stops. A new mega and ramps is pretty cheap now a days. But if your looking for a new board then I recommend you check out rwg research on YouTube and look up the oversized delta. OSD build he is currently building and testing. He shows how the mega is just not enough for the delta calculations and autolevel and run the lcd while reading info from memory card. Check out the duet board, new ones have wifi. The lcd you have can be used with it and in future can upgrade to a full touch screen interface. But if all works and also want the interface check out octoprint, I support on patreon, and or repetier host. There are others so be careful in your choice.
