Calibration issues #41

Open Casssss opened 6 years ago

Casssss commented 6 years ago

Hi all,

I am using an arduino 2560, a RAMPS 1.4 and an inkshield (http://nicholasclewis.com/projects/inkshield/theory/) to operate the pwdr printer.

I have been trying to understand the firmware and processing GUI in order to calibrate the printer but despite best effort, I am still quite newby when it comes to software. The usersmanual states ''Currently, the only way to change the parameters is by hardcoding them in the Arduino parameter declarations'' To me that sounds like the stepsize should be changed in the firmware, however I can only make the steppers move using the Processing GUI individualy which doesn't necessarily have anything to do with the declerations in the firmware. Can someone point me in a direction?

Help is appreciated, Cas van Schaik,

The stepSize van be changed in the Arduino firmware source, after that, it needs to be uploaded to the Arduino Mega.

The stepSize determines how much the printhead moves, basically controlling the printer resolution.

If you were able to move the steppers in the GUI, the connection/interface between Arduino and RAMPS is fine.

You mention you’d like to calibrate your printer, could you point out what exactly you’d like to do?

Thanks, Alex

Hi Alex,

I thought the stepsizes had to be changed to make the stepper motors move similar distances relative to each other which is what I meant with calibration.

Initially I thought the jogsteps of the GUI were defined in the firmware but that doesn’t seem to be the case since the GUI and firmware work fine individually, I can’t seem to connect the GUI with the serial port after uploading the firmware, an error pops up when I click the serial port but only if the firmware is running already.

There is one other thing that makes me scratch my head, I got the inkshield from N.L. and the RAMPS board, I am trying to stack them both onto the MEGA. When I look at the picture underneath it looks like the inkshield is stacked on the Arduino but the RAMPS isn’t. May I ask how you managed to connect both boards to the MEGA?

[P4118757] Thanks for your quick reply, it helps a lot.

Kind regards, Cas van Schaik

Instead of a RAMPS, I've used a custom proto shield...

Please send me a PM, so I can help you in Dutch :-)

I have send an Email to pwdr yesterday if that's what you meant by PM, I am not sure if it arrived.

Pwdr commented 6 years ago

Mmm, I cannot find your email. Did you use the address mentioned on pwdr.github.io?
