No starts printing

[ingsergio]

Best regard.

After loading the new firmware and all the xyz axes, limit switches etc. It works perfect. I went to print my first 3D solid and I spend a few problems:

1) Heating the nozzle 235, and is not kept low and 221 goes up and down .... Not stable.
2) When the temperature of the nozzle 235 is placed and 95 to give print bed and tells me that printing is finished (At no time axis moves)

I can do?

I thank you for your collaboration.

thanks

You should slice before printing, the printer can not print without generating g-code. You should click" Slice with slic3r"(My slicer software is slic3r).
If you want to set the slicer, you can click "configuration", you can refer to this page for more details:

You can stabilize the ripple in the temperature with PID tuning of your printer. Every printer, even with the same exact parts react differently due to different environment, build tolerances, component tolerances, etc. etc. These 'other' variables affect the way your printer heats and cools which impacts its temperature stability and ultimately how nice you can get your prints to look.

PID Autotune is built into Marlin firmware and can be invoked by executing:

M303 E0 S200 C8 (Nozzle must be COLD before executing this)

from the Repetier-Host "Print Panel" tab (otherwise known as Manual window for "Windows OS" people)

Monitor the console window (lower left of Repetier-Host window) and wait for Autotne to complete. When auto tune is complete, the final values of "Ki, Kp, and Kd" will be displayed. Write these down. Go back to the Manual screen an execute:

M301 IKi PKp DKd (plug in your previously Ki,Kp,Kd values you wrote down.

If you have EEPROM enabled, you can save these values by executing:

M500

If not, then you have to manually insert them into the firmware "configuration.h" file and re-flash the board.

To PID Autotune the bed execute:

M303 E-1 S70 C8

Run through the same process as with the nozzle above but this time execute:

M304 IKi PKp DKd

Again save to EEPROM with:

M500

or save manually to firmware so it's always there every time you print.

Hope this helps.
