<![CDATA[SoliForum - 3D Printing Community — Soliprint Default Temperature?]]> https://www.soliforum.com/topic/10348/soliprint-default-temperature/ Wed, 18 Mar 2015 20:32:17 +0000 PunBB <![CDATA[Re: Soliprint Default Temperature?]]> https://www.soliforum.com/post/90064/#p90064 I believe soliprint can only change the contents of the EEPROM. Not a parameter in the Firmware i.e thermistor type. That change has to be complied then flashed.

As for the overtemp, In the FW there is a MAXTEMP parameter which is set to 300C. As what the jacket of the heater cart and the thermistor wires are, That's a good question- But I doubt that's PTFE. It has a slight gritty/rubbery texture.

I print at 250 for the first few layers and then take it down to 240..and then 230.
Can the Solidoodle Press get damaged from this?

You'd hope SD has the firmware set up to prevent overtemp. Not impossible.

The weak point might be the plastic insulation on the heater wires. If it's PTFE and gets into the 230s (C) it could break down into some fairly toxic fumes. (Check with a temp probe, being careful not to short anything?)

Next up would likely be the temp sensor, but I don't know what part they're using.

Also, you'll find at some temp you'll overwhelm the heat break and jam.

Also makes for crisper corners and usually smoother surfaces, and less chance of coking the filament. With lower temps come with less interlayer adhesion and a higher Vref on the extruder to push out the more viscous plastic. (Definitely a balancing act as a hot direct drive stepper causes problems too.)

My first SD prints tended to have occasional little browned blobs of overcooked ABS in them.

It's also possible SP 1.1 fussed with the firmware termistor settings, changing the relationship of reported vs. actual temperature. (feels less likely, but it's all just speculation.)

The distance should be approximately the same for all stock Presses, so it shouldn't vary all that much between units.

Correct...it should not vary between units; but the actual melt temp will always be higher than what the thermistor reads.  For example, my SD2 with the stock hot end has about a 25 degree difference.  I set to 205 to extrude at 230...

Doesn't explain why Soliprint changed their default temp as stated by OP...

I have to set it every time. I am guessing some units are configured such that 215 is enough (or 215 is really 240 due to stepper trim pot issues).

I print at 240 for the first layer and 220 thereafter (Well, until my heat bed died. Now I just wait for SD support). 240 is pretty toasty as a minimum temp. Try checking your stepper trim pot to see if you're getting enough current to your stepper. (Plenty of posts on that - I won't repeat here.)

I believe that version 1.0 was ~245. What is the reason for the change? My Press won't extrude consistently at anything less than 240.

Any input?
