switched to cura for first print

Recommended Posts

Hey guys,

So based on the response from my last post:


i switched to cura.

Previously i got to the print stage, after configuuring the end stops and extruding some plastic.

But with cura, i cannot get past the ultimaker checkup.

It fails on:

"Error: Missing reply to Deactivate steppers (M84)."

"Possible cause: Temperature MIN/MAX.\n Check temperature sensor connections."

I have turned off the machine a few times now and checked all the connections to the electronics , with no luck of getting past this problem.

I saw in the out put that i was getting a None type return so , i added some debug prints that im hoping might help for getting a solution to this:

Connecting to: COM5 250000

DoCommCommandAndWaitForReply:cmd None

DoCommCommandAndWaitForReply:replyStart start

line: start

DoCommCommandAndWaitForReply:cmd M84

DoCommCommandAndWaitForReply:replyStart ok

I am running on winxp 32, on a centrino duo chipset, with whopping 3.4gb of ram..

Please let me know if there is anything else i can provide to help figuring this out.

Ok, so the question then becomes.

if i calibrated the machine and build platform in replicatorg 24 with the standard firmware.

now that im using cura, and updated to marlin, how do i re calibrate? or do i need to

i notice that cura doesnt have a control panel type thing that rep g has... soo?

Calibration from RepG24/25 (old way) and Cura/RepG34 is very different. The new was is called "volumetric", but the default calibration from Cura will most likely produce very decent results.

For printing and directly controlling your machine you can use PrintRun, which is packaged with Cura (different start menu shortcut). It offers a lot more features then the very basic Cura printing interface.

EDIT: But lots of thanks for those debug messages. They confirm what I suspected. There should be a delay after recieving the "start" line, and sending the M84. Because the firmware might not be fully up and running (most likely due to SD card failing to initialize). As it should have replied "ok" after the PID settings.

    • "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.
