\"\"<\/a><\/figure>\n\n\n\n

\nAfter getting Mr. Wallace out of the closet and actually getting it \nprinting, I’ve been rather deeply interested in 3D printing again. \nI still had some spare parts and we were planning on building out my son\n a Wallace based printer for his college needs so I started assembling \nthe basic parts.\nMy goals were to use the improvements I made to Mr. Wallace and expand \nthat a bit by adding a direct feed extruder and a bowden setup to lower \nthe X carriage weight.\nPotentially this would drop the wobblies from the extra mass moving \naround out there and just looks a bit cleaner anyhow.\nI also wanted to test and use one of the new inductive bed sensors I \npicked up and try out auto bed leveling.\n<\/p>\n\n\n\n

Once Mr. Wallace was doing well, I really didn’t want to tear him all up to try out these new things so I printed out the parts needed and threw Gray Hair together. The name isn’t anything special, just reminded me of that with the black and silver trimmed out colors… and when I look in the mirror daily. <\/p>\n\n\n\n

Why I Like the Wallace<\/h2>\n\n\n\n
\"\"<\/a><\/figure>\n\n\n\n

\n\nAs noted in the Mr. Wallace post, I really like the Wallace design. Easy\n to understand, simply to put together, AND easy to expand all the axis \nas desired for the most part.\nAt first I tried a normal 200×200 heat bed but I built the core base to \nhandle a 200×300 as that was a long term desire. \nAfter burning up a RAMPS connector and a MOSFET with the smaller bed \n(obviously something screwed up there) I put the longer bed on it early \nwhich is fine.\nBut again, it’s very easy to open up any axis to fit whatever bed you \ncan come up with on the Wallace.\nI know there are some limits in regard to the Y being too long and the Z\n too wobbly but it’s a very nice simply design by “whosawhatsis”.\nThe pic shows how simple the base is on this design with simple threaded\n and smooth rod connections.\n\n<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

\n\nAfter a very short time you can have the frame together. Key is getting \nyour X width correct so you can get full travel on your 200mm bed.\nI missed that slightly based on my setup but I’m at 190 so close enough.\n With mechanics done adding the rest is pretty straight forward as well.\nNo magic or hard to measure, square or calculate areas for the most \npart.\n\n<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

\n\nGray is a bit different than Mr. Wallace as noted above in that it uses a\n bowden extruder setup as well as the standard vertical stacked X \ncarriage arrangement.\nIt also has a LJ18A3-8-Z\/BX inductive sensor for the Z axis which is \nalso used for auto bed leveling features.\nRight now I am using small sections of aluminum tape for the leveling \nand Z homing sensing but the inductive sensors appear to work through \nthe glass to the heat board.\nI will have to change things around at some point and see if it will be \nconsistent enough to use all the time.\nWith Z Safe Homing set there shouldn’t be any issues of crashing the \nheat bed since Marlin will use the spot you set as your safe homing \nlocation.\n<\/p>\n\n\n\n

\nThe bowden setup lowers the hot end overall mass which should allow for \nfaster print speeds and smoother overall prints. We will see however.\nAdditionally the top Z clamps I modified to hold the backbone support, \nalso provides for the bowden extruder and can also hold another extruder\n on the other side when I want to give dual extrusion a try someday.\n\n\n\nFor now I’m running a combo cold end fan \/ part cooler fan which seems \nto be working fine. \nIt may be best in the long run to have a different fan for parts cooling\n however to allow the firmware to better control when parts cooling may \nbe needed.\nThat would just add more mass to the X carriage however too so it’s all a\n balance.\n\n<\/p>\n\n\n\n

Sample Prints<\/h2>\n\n\n\n
\"\"<\/a><\/figure>\n\n\n\n

\nHere are a few sample prints from Gray Hair. \nThe 3D Benchy boats go from the actual 2nd print on the printer without \nany part cooling and default settings through print #4 that cleaned up \nmost of the overall issues.\n\n<\/p>\n\n\n\n

\nNext is the final benchy using a .1mm layer. Still a few oddities that \nare likely due to parts cooling control or hot end temp drift so more \nwork to do but quite acceptable.\n\n \t\n<\/p>\n","protected":false},"excerpt":{"rendered":"
