Load capacity

What is the load capacity of the Valleman k8200? in case I want to replace the nozzle by a different print head.

Not sure what you mean with ‘load capacity’…

My meaning is: how much weight can the aluminium frame can carry if I replace the extrusion nozzle unit by a different unit? so I need to check what is the weight limit for such a unit.

Sorry, this has not been determined.
Please experiment.
