No problem, setting Octopi is as easier as download the zip file from https://octopi.octoprint.org/latest . Before install it on an sd card, edit the config inside the Zip file wtih your ssid and password for your wifi, you’ll have to coment out // from the option that is more appropiate (probably WPA). Now copy all the contents from the Zip file to the SD Card (with the edited config file) and fire it up with a monitor / tv, touch screen on the pi and keybard will ask you to put a password and login, thedefault is user: raspberry password: pi, then input sudo raspi-config so you can change user name and password, expand the file system and make it boot automatically with your user name and password. Now is configured reboot, connect the usb port to the 3d printer (now you don’t need a monitor or keyboard for the Raspberry Pi) you can access octopi from your web browser on http://192.168.1.167
if you have a compatible webcam or Raspberry Pi cam you will also be able to stream under control tab in Octoprint after enable time lapse. Oilaaaaa!!! Job done…
I think I covered it all, is fairly easy to do.
OH wow tha ks! I will be looking into is over the weekend
The firmware doesn’t know about steps per mm. The slicer (makerware or GPX for anything else) converts coordinate dimensions into step counts and that’s whats in an X3G file.
From the GPX source code though, we can see that the standard Replicator 1 Dual (which is the profile we use for CTC) is 94.117647 steps/mm.
Extruders are 1600 max feedrate, 96.275201870333662468889989185642 steps/mm, 3200 microsteps per revolution.
(all this info is taken from std_machines.h in the GPX source; the structure definitions are in machine.h)
If it may help you, i’m attaching screen shots of all the EEPROM settings from ReplicatorG.
Thank you, that confirms what I’d thought as I found the same settings under the .json files in makerware, although I thought that maybe the ctc steps are different to the makerbot but if uses the same settings I should be able to code Marlin RC7 bugfix. Once is coded and test it I will upload it into this thread so it is a bit easier if anybody wants to convert to ramps or MKS
do you happen to have the cura profile settings for octo print?

You do can go into settings-plugin and there is Cura plugin although I have not yet used it with the CTC as the firmware is not finished yet, sorry

If you look at my last update I had a problem with printing in the centre of the bed but I belive is on the cura settings. I am going to have another play with the CTC Firmware & Cura in the next few days, just been busy.
If you manage to sort it before me, please do let me know where I’ve been going wrong??!!

Also the reason that is homing to centre of the bed is because the safe_homing option was enabled as I was thinking to put a probe for auto bed level. I’ve changed some settings in the firmware so maybe works better for you now, I’ve re-uploaded the firmware… give it a try

I have already changed some of those settings and reuploaded it after sent my response to your comment. Would you mind sharing your S3D Profile as it will save me time having to make one. I should be able to put all my findings by the weekend when I have a bit of spare time.
There is some changes that you need to make to your code as Z_SAFE_HOMING is only defined when a probe is on use and the reason that bed centre is not quite right is because I input the code wrongly, all these chaanges should help you to get it right as I hava just uploaded the code to mine and seems to work (although I will test it throughly later on this week):
// @section homing
// The center of the bed is at (X=0, Y=0)
#define BED_CENTER_AT_ (151.98, 72.50)
#define MANUAL_X_HOME_POS -151.98
#define MANUAL_Y_HOME_POS -72.50
#define MANUAL_Z_HOME_POS 0 // Distance between the nozzle to printbed after homing
//#define Z_SAFE_HOMING

Going to try your settings, could you share the Simplify3D profile please…

Dude i love the idea of those mks touch screens for the ctc particularly the print resume on power loss feature, i have read you can just plug them into aux 1 on the 1280 boards and upload firmware to it to work? was this the case for you? how hard was it to fit one and what steps did you have to take?
Do you have the latest? I have a CTC with the dual M8 extruders and a bad board. I have an Arduino Mega 2560 and RAMPS 1.4 like I used on my Core-XY but need something tailored for teh CTC without spending many hours reinventing the wheel.
Hi,
I’m now attempting this conversion myself.
How did you get on with it in the end?
The thing i am currently usure about is stepper motor currents; i have no idea what the stock motor max current is. Do you have any idea?
thanks
jon
Hello all sorry for my english. What is the voltage of your drivers please? thank you
hello is this the latest firmware or does it still need some work
hi you don’t have the wiring for the ctc hot bed figured the power but 4 heatbed senser wires
