Unresolved LCD screen up-grade issue

I up-graded the ROBO with the LCD screen/controller ( ). I get error messages about exceeding temperature pre-sets. How do I change these?

 

What are you trying to set it to?

If you run an all metal hotend you can flash a firmware with the temp limit raised to 290

 

I put the original print head back on the ROBO as the E3D seemed to plug up consistently. I used the heating element from the E3D with the stock head. It works much nicer. Problem is that using the LCD screen, I can only get the bed temperature up to 100C and the print head to 200C. I like to use 110 and 235 for ABS.
Mike, I think you helped me out last summer with team viewer and flashed the firmware for me to reach 290C.

Cheers,
John

 

Getting that bed up to 110C without a SSR or upgrading the voltage would be difficult.

I remember helping you with your firmware. If it can only get to 200C then it might be a loose thermistor not making contact with the internal metal.

 

Mike: Possible. Any idea why I can't get the bed up to 110C using the LCD? I can't dial it past 100C.
Mark: Yes, I used to use both programs but now I'm using Cura because it allows me to save to a SD card easily. When I use a USB cable with the laptop, I run into stalling problems. Damned if I do, damned if I don't.

 

Hmm the temp limit might be preventing that. Do you still have the firmware I made for you? You can check in the configuration.h file

 

Mike, remind me again how I check the firmware.

 

In the Arduino IDE software open up the .ino of the same name as the folder.

With the firmware open navigate to the Configuration.h tab

In this tab do a ctrl+F for 275

This should bring you to this section:

Code:

// When temperature exceeds max temp, your heater will be switched off.
// This feature exists to protect your hotend from overheating accidentally, but *NOT* from thermistor short/failure!
// You should use MINTEMP for thermistor short/failure protection.
#define HEATER_0_MAXTEMP 290    //robo
#define HEATER_1_MAXTEMP 275
#define HEATER_2_MAXTEMP 275
#define BED_MAXTEMP 85

Your values are probably different.

You want to change the BED_MAXTEMP value to around 115.

If you have a connector on your Y axis cabling I do not advise running the bed at 110C, you should cut out the connector and jumper the wires together. Otherwise you may have issues with the connector shorting.

 

Mike, the only tab I see is "sketch_jan08a" No configuration.h tab.

 

You gotta open the firmware file, might be best to do another teamviewer

 

Probably. Are you free tomorrow evening?

 

Sure, just message me on skype

 

OK, I should have your number.

 

Sorry but are you having problem with the LCD that has 15c difference or not?

 

Just got in from work, crazy day. How about if we try sometime tomorrow?

 

Sure. I should be around.

 

Things are looking up. Had two decent prints. Thanks for your help Mike. I don't know if ROBO3D has you on the pay role bu you do make their products easier to use.
Cheers.
