Problem with Printing Blobbing, from Octoprint Pausing Transmission of Serial Data

Post by bob195558 » Mon Mar 02, 2020 1:44 am

Problem with Printing Blobbing, is caused from Octoprint Pausing Transmission of the Serial Data
Printing Blobbing_a.jpg
When using a Raspberry-pi to run Octoprint, using a USB cable connected to your 3D Printer,
you may get "Printing Blobbing".
The Raspberry-pi, running Octoprint, will pause the Printing-Data-Transmission when it is doing other data processing.
So the stored Printing Data in the pi buffer becomes completely depleted so that your 3D printer then has no date to process.
This time of no data is causing your printer to wait for more Printing-Data to be sent.

See below where Tim at TH3D explains this problem with much more detail.

If you have the EZBoard, Tim has the new version of EZFirmware released.

Note: a message from Tim Hoogland "TH3D",
We've updated both our firmware branches for the EZBoard and stock machines
with the new buffer sizes to help with Octoprint slowdowns.
You can download them from our website or if you are using the EZBoard the EZFirmware site it is updated as well.

You can find updated firmware here: https://www.th3dstudio.com/knowledgebas ... e-package/

You can find here info about flashing Tim's new TH3D EZFirmware (version: TH3D U2.R1.B1),
which increases the buffering size (stored data size) for the Printing Data received.
