Dimension printer automation?
Hi,
How should I proceed with a Stratasys Dimension printer? It seems to decode correctly when I set it to “prodigy” printer type, but won’t work with other types. The problem is with the automation script, here is what I get when I connect a cartridge’s EEPROM:
New device detected <23d985710100006f>.
Error! verify machine type?
Details:
Traceback (most recent call last):
File "build/bdist.linux-armv6l/egg/stratatools/helper/rpi_daemon.py", line 37, in on_new_cartridge
c = cartridge_manager.decode(machine_number, eeprom_uid, read_bytes(eeprom_path))
File "build/bdist.linux-armv6l/egg/stratatools/manager.py", line 54, in decode
cartridge = self.unpack(cartridge_packed)
File "build/bdist.linux-armv6l/egg/stratatools/manager.py", line 112, in unpack
raise Exception("invalid content checksum: should have " + hex(struct.unpack("<H", str(cartridge_packed[0x40:0x42]))[0]) + " but have " + hex(self.checksum.checksum(cartridge_packed[0x00:0x40])))
Exception: invalid content checksum: should have 0xf900 but have 0x9e0c
Do you have an idea on what I could do to make it work? Thanks!
I’m trying a few things to try to make it work and I’ve rewritten the on_new_cartridge() function of the helper/rpi_daemon.py file.
When calling cp ~/eeprom_new.bin /sys/bus/w1/devices/w1_bus_master1/23-xxxxxxxxxxxx/eeprom, I randomly get this error:
cp: error writing '/sys/bus/w1/devices/w1_bus_master1/23-xxxxxxxxxxxx/eeprom': Input/output error
Why is this happening? It’s the only thing that’s blocking me right now. If it can be fixed I’ll post my working script.

Where you able to solve the Check sum error? I am having the same issue
No I haven't worked on it again but am still very interested about resolving the issue!

Dimension uses the "prodigy" type. What specifically are you trying when you get the checksum error?
