Great idea guys. I am about write an article on the future of 3D printing. Will be great place (mag) to publish.by 3eality - RepRap magazine
Hi, Are there any RepRapers from Melbourne Australia?by 3eality - General

Thanks for the input guys. I have tried at 175 and 180 - There is no extrusion. Simply it just doesn't flow A very slow flow occurs at 195 and some comfortable flow at 208. However even at this temperature the PLA is not flowing continuously. After I give 'Run Extruder' command it takes a while to flow and it flows after the extruder stops. I assume this due to the pressure locked in the tuby 3eality - Reprappers

I have bought my Prusa from 3DStuffmaker. I have assembled it and am having similar problems like you: 1. the extruder doesn't extrude coby 3eality - General
Thanks for clarification. My biggest problem is the flow of PLA. It is not flowing continuously. It just stops at its own wish. Below are the reasons I am thinking. Can you help me if I am thinking right? Possible reasons: a. The extruder speed is not set properly b. the tube type extrusion is not great. I am suspecting the pressure in the tube (from hanging extruder to hot end) is changingby 3eality - Reprappers
Thanks Bob. I have now tested a simple print at 800 speed and first time got something like a printout . I will try at 500 speed tomorrow. I am assuming both of us are referring to XY speed. While observing it closely the main reason appears to be the lack of consistent flow of PLA. By consistent I mean two things: 1. A continuous flow is not achieved. Sometimes PLA doest flow and some tby 3eality - Reprappers
Thanks for the responses guys, I have run the print after adjusting the height and watched closely. The problem appears is not with sticking to the kapton tape. Instead the PLA is not flowing consistently. The flow is erratic and interment. While I am testing with 'Run Extruder' with 1500 speed, some times it flows and some times it doesn't. Occasionally there is some oozing. Any help?by 3eality - Reprappers
Hi, I have finished assembling my Prusa. Configured the gen6 board and am using Repsnapper. Everything runs smoothly (X, Y, Z, Extruder etc). Two things I am not able to work out: 1. consistent flow of PLA from the hot end. 2. PLA is not sticking to the print board (acralyc with Kepton tape) When I run the extruder for test, some times PLA flows smoothly and some times it starts to curlby 3eality - Reprappers
Hi JJ, How are you progressing. Are you able to get it through or did you end up selling. Let me know if you are planning to sell.by 3eality - Reprappers
