reset firmware?

Recommended Posts

Hello all,

I was trying out some new firmware, and I am stuck.

I was able to work with replicatorG and the motors do work, no heating nor extrusion.

Then I tried out some newer firmware, but now I cannot connect anymore.

It says:

Attempting to reset RepRap (pulsing RTS)

Unknown: **********HERE SOME STRANGE SYMBOLS

Any help ?

Thanks,

Peter

The firmware from:

http://daid.eu/~daid/marlin_build/

is recommended.

But if you want to print from RepG you need to:

-Set the baudrate to 57600

-Disable the "software endstops"

-"Steps per unit" for "E" needs to be 14 with the RepG from Ultimaker.

Or, you could upgrade to the SkeinPyPy Beta3:

https://github.com/daid/SkeinPyPy/downloads

Which helps you installing the right firmware, and allows faster and better slicing.

The first link I gave you can build a firmware for you, it also contains a batch file that helps you in changing the firmware, this always works, even if RepG cannot connect.

The settings I said you need to change in the link I gave.

Hey Daid,

 

The firmware from:

http://daid.eu/~daid/marlin_build/

is recommended.

But if you want to print from RepG you need to:

-Set the baudrate to 57600

 

I have it set to 115200, it works fine.

I have my software stops enabled, is that because I use Netfab?

I thought the E14 was only for Netfab.

Hi petermeuris

Use Daid's link you configure and upload your firmware from there.

You configure it, download the zip file, run the batch file, enter your com port, ie. COM4 and it does the rest.

It's great and so is that version of Marlin.

So I followed your first link, created the software uploaded it, but is tells me:

avrdude: stk500v2_ReceiveMessage(): timeout

avrdude: stk500v2_ReceiveMessage(): timeout

avrdude: stk500v2_ReceiveMessage(): timeout

avrdude: stk500v2_ReceiveMessage(): timeout

EDIT: Restarted the ultimaker and ran the uploader again, this uploads the software

And I can connect again with repG !

Thanks !!

Still no heating nor movement in the feeding motor though, the rest works.

So I have still work to do :-)

The extruder (feeder) motor won't move unless it's on proper temperature (cold extrusion prevention)

However, in RepG26 the direct control of the extruder is broken, so you cannot use that to test the extruder. Heating should work however. Be careful, it can be the heater, or the sensor that's not working. If the temperature sensing is not working then you could damage your machine!

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
