another error: printer set into dry run mode before restart

Post by dajay23D »

Hello,

Been awhile! First, big ups to Rostock Max V2. what a work horse!! even, though i never perfected the bed leveling to completely utilize the 280mm, i made tons of great prints in a small diameter that i was able to level. on top of that, made some money too! made more than what the printer is worth for sure.
Long story short, i tried to upgrade to a more recent firmware and encountered issues with the horizontal radius. It was a lot different and i keep grinding into my bed. The center and the outside was good, it seemed like it was making a deeper arc in between. I did some emergency shut offs. Unfortunately, i forgot about the emergency button on the LCD face(not sure if it makes a difference). I just flat out shut the printer off. I did this about 4x, and after, this error came on. Before i do a full tear down and cutting wires, is there a way to do a "restart" like it says? I uploaded the old firmware and the horizontal radius is a lot better, but didn't solve this error. Nozzle/bed temp: def shows up on the LCD. Some searches are indicating it's one of the thermistors. I don't have a multimeter to check. So i'll just replace them. Before i do that, just wondering if anyone has any easy recommendations that i can try? Can the shut off cause a short or damage the thermistors? I've been beating the hell out of this printer, so it's been good for 5 years! I'm assuming my shut off caused this problem, but not sure.
Thanks!

If you address the thermistor issue, the "dry run" message will likely go away.
I would highly recommend you buy yourself a multi-meter. They can be had very inexpensively at places like Harbor Freight, or even your local auto parts dealer. Note that when checking a thermistor, you need to disconnect the leads from the RAMBo in order to prevent the RAMBo from interfering with the reading.

If you've got a bone-stock v2, there's nothing really to be gained from updating the firmware. An important thing to note that if you DO change the firmware, you need to wipe the EEPROM first, otherwise old settings could be left behind, become corrupted, and cause weird things to happen. :)

If you're in the mood for doing upgrades, I can't recommend the Duet/SE300 combination enough. Unless there's something drastically and physically wrong with your printer, you WILL be able to print right to the edge, first time out of the gate. :)

You're welcome! I forgot to mention that you need to use v1.6.0 of the Arduino IDE to build the firmware, otherwise weird operation can occur. They made some change past that version that can cause issues due to the large size of the RAMBo firmware.

now you got me thinking about this upgrade and researching it! lol Looks like lots of Duets are sold out though. I'll do it after i fix my current issue.
V2 been so solid i didn't want mess with it. I decided to upgrade because it had this lingering issue where if i stopped printing for a few weeks, it would go out of wack like freeze in the middle of a print or calibration would be off. I would need to clear the EEPROM and re-upload firmware and it would be good again.

Replaced the hot end thermistor, so it's not that. I'll have to buy a thermistor for the bed now.
I did clear the EEPROM. Maybe the 1.60 Arduino is my problem. I just looked and I'm using 1.8, doh!

Filastruder is usually the go-to source for Duet Wifi boards.

Your issue with stability may indeed be related to the compiler version - I've seen some truly odd behavior due to that issue.

I also have the 1.8.2 compiler. did going back to the 1.6.0 fix your issue dajay23D?
