Are the kinematics actually any different for them? I think they would be the same. The belt routing between the joints and the carriage is the same for both on the front side of the machine, so I think the actual movement of the carriage relative to the joints is the same for both. The difference between them is only how belts are routed to take up the slack on the back side of the gantry. The H-bot has a single continuous belt loop through the gantry (not connected to the carriage), where the corexy separates the joint belts and sets up each joint belt loop on the back side of the gantry as a to mirror the front.

There is support for core-xy: https://nam04.safelinks.protection.outlook.com/?url=http%3A%2F%2Flinuxcnc.org%2Fdocs%2F2.8%2Fhtml%2Fman%2Fman9%2Fkins.9.html&data=04%7C01%7Ctoddz%40pgrahamdunn.com%7Cdab0c1fe7fc640ce6bc008d9bf3fa5ab%7C5758544c573f47cebee96c3e0806fb43%7C0%7C0%7C637751102358558208%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=hx3K%2BSOaJh69B%2FXQP2mCGddrf3qtkOMuOssB3YxE0VY%3D&reserved=0 I don't see direct support for H-bot. (But I think that corexy is probably better, as it relies less on the stiffness of the carriage) What do the equations for H-bot look like? -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." - George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list [email protected] https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.sourceforge.net%2Flists%2Flistinfo%2Femc-users&data=04%7C01%7Ctoddz%40pgrahamdunn.com%7Cdab0c1fe7fc640ce6bc008d9bf3fa5ab%7C5758544c573f47cebee96c3e0806fb43%7C0%7C0%7C637751102358568198%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=2udjB8yOwHOhXOLLopke2trXX52kNJ1wPjZWPlyCZ5s%3D&reserved=0 _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
