EZR Struder fail
My EZR Struder motor is heating up and is causing the gear to got so hot, that it makes the filament super soft. Then chews through it, then starts pushing and jamming up the entire EZR Struder set up. I've finally got the gear in the correct position but now this is happening and I can't even touch the motor due to it being to hot. Any ideas out there? Motor has an Automation Technology sticker the back.

Re: EZR Struder fail
Sure would be nice to have a little more information,,, most importantly, What printer are you using, and if a V2 RoMax, when was it bought from SeeMeCNC?
At one point in the production life of the V2, they changed which steppermotors. The new ones required less current, and the current limiter settings had to be changed.

Re: EZR Struder fail
What is your motor current set at? Line 438 or so in Configuration.h. Should look something like this:
Code: Select all
#define MOTOR_CURRENT {140,140,140,130,130}

Re: EZR Struder fail
line 57 for dual extruder repeater firmware is
was (140,140,140,130,0) I had issues with EX0 heating up
I was advised to change my settings to (140,140,140,145,145) by SeeMECnc support issues happened faster and chewed through the filament before a .25" in height was reached by the printer. Before is was after .75" but before .2" in height. I think (145) is the wrong direction.
Thoughts?

Re: EZR Struder fail
The line you posted is the catchall in case motor current doesn't get defined by your printer. The line you are looking for is down in the Rostock V3 printer definition (line 438 in current firmware). The last line listed below:
Set your's to match that (it sets motor current for both extruders to 130) and see if it helps.
Code: Select all
#elif PRINTER == 5 // Rostock MAX v3
#define FAN_BOARD_PIN 6 //Cooling fan on RAMBo board
#if NUM_EXTRUDER == 1
#define MOTOR_CURRENT {140,140,140,130,0}
#elif NUM_EXTRUDER == 2
#define MOTOR_CURRENT {140,140,140,130,130}

Re: EZR Struder fail
Just check that line, Extruder EX==2 was set up like this with no issues
{140,140,140,145,145)
#1 was never changed going to mimic those setting and give it a try. If they fail again, I will drop them to {140,140,140,130,130)
are the newer motors supposed to increase or decrease Current?

Re: EZR Struder fail
The new motors run lower current

Re: EZR Struder fail
So what is the actual value that is being represented here? if I input the value of 130 what is the actual current going to the motor?

Re: EZR Struder fail
The values are out of 255. I think the rambo has 2amp stepper drivers so the running 130 for the extruder would be:
2000mah * 130/255 = 1020 mah = 1.02 amps
2000mah * 130/255 = 1020 mah = 1.02 amps

Re: EZR Struder fail
I'll be changing my values this afternoon. I haven't had an issue all weekend with them at
#elif PRINTER == 5 // Rostock MAX v3
#define FAN_BOARD_PIN 6 //Cooling fan on RAMBo board
#if NUM_EXTRUDER == 1
#define MOTOR_CURRENT {140,140,140,145,145}
#elif NUM_EXTRUDER == 2
#define MOTOR_CURRENT {140,140,140,145,145}
Changing to this after I take a temp reading.
#elif PRINTER == 5 // Rostock MAX v3
#define FAN_BOARD_PIN 6 //Cooling fan on RAMBo board
#if NUM_EXTRUDER == 1
#define MOTOR_CURRENT {140,140,140,130,0}
#elif NUM_EXTRUDER == 2
#define MOTOR_CURRENT {140,140,140,130,130}
And why is that on Extruder #1 the last current is set to "0"? and not that way for Extruder #2
Just seems odd to me.

Re: EZR Struder fail
It's set that way because when you only have 1 extruder, we don't want any motor current going to the 2nd (an nonexistent) extruder

Re: EZR Struder fail
Changing these settings made a huge difference.

Re: EZR Struder fail
I did this:
AliExpress heatsink and thermal glue
(This is after trying the variable adjustments in the firmware and still having problems on longer/quick prints)
