PLA to ABS and ABS to PLA

[geeks 1]

Hello,

 

My bed is always off ... I can not print objects.

 

Before receiving the new hot bed part, which me time to my question. I think pass of PLA to ABS and vice versa.

 

In context, what does it do to remove the PLA and replace by the ABS?

 

Y t to it a risk that the nozzle is clogged?

 

For those who have tried, what was your difficulties encountered?

How did you overcome the problems?

 

Thank you for respond.

Alex.

Tried my First ABS prints the other day and had to heat the bed to 99'c could not achieve any higher. I also used brim for some thinner parts. Used built in ABS settings and things printed fine. when returning back to PLA the UM2 knows that you have been using ABS previously so turns the nozzle temp up to 260'c during the material change. I went to advanced settings and moved the PLA at 260'c to make sure all the black ABS was removed from the nozzle. I had no problems with blocked nozzles.
